LUPRAGEN N 205
LUPRAGEN N 205 is a tertiary amine that primarily promotes the urea (water-isocyanate) reaction in flexible and rigid polyurethane foams.
LUPRAGEN N 205 can be used in all types of foam formulations. The strong catalytic effect on the blowing reaction can be balanced by the addition of a strong gelling catalyst. If amine emissions are a concern, TOYOCAT ETSlow-emission alternatives are available for many end use applications.
Bis(2-Dimethylaminoethyl)ether (LUPRAGEN N 205) is a colorless to yellowish liquid, with an amine-like odor. LUPRAGEN N 205 is also miscible with water.
Bis (2-(dimethylamino)ethyl)ether (LUPRAGEN N 205) reacts as a base. Reacts exothermically with acids. May form explosive peroxides upon exposure to the air.
Formula of LUPRAGEN N 205: C8H20N2O
Molecular weight of LUPRAGEN N 205: 160.2572
IUPAC Standard InChI: InChI=1S/C8H20N2O/c1-9(2)5-7-11-8-6-10(3)4/h5-8H2,1-4H3
IUPAC Standard InChIKey: GTEXIOINCJRBIO-UHFFFAOYSA-N
Bis(2-(dimethylamino)ethyl)ether (LUPRAGEN N 205) appears as a clear or yellow liquid. Bp: 188°C. Toxic by inhalation, by skin absorption, ingestion, and eye contact.
DMAEE (LUPRAGEN N 205) vapor was readily absorbed at a constant rate, slowly eliminated mainly by urinary excretion, and without preferential specific organ/tissue accumulation.
DMAEE (LUPRAGEN N 205) is used primarily as a catalyst in the manufacturing of polyurethane foams.
NIAX Catalyst ESN, its components, dimethylaminopropionitrile and bis(2-(dimethylamino)ethyl)ether (LUPRAGEN N 205)
In May 1978, OSHA and NIOSH jointly published the Current Intelligence Bulletin (CIB) 26: NIAX Catalyst ESN. In this CIB, OSHA and NIOSH recommended that occupational exposure to NIAX Catalyst ESN, its components, dimethylaminopropionitrile and bis(2-(dimethylamino)ethyl)ether (LUPRAGEN N 205), as well as formulations containing either component, be minimized.
Acute Exposure/ Unoccluded application of 10 uL of undiluted LUPRAGEN N 205 (DMAEE) to the skin of rabbits produced marked local necrosis. More serious skin lesions were produced when the material was kept on the skin under occlusive dressing for 4 hr.
Acute Exposure/ LUPRAGEN N 205 (DMAEE) was applied to the eyes of rabbits undiluted or as a 1%, 5%, or 15% aqueous solution. When administered undiluted, LUPRAGEN N 205 (DMAEE) produced extensive corneal injury, iritis, severe conjunctival irritation, and chemosis. A 15% solution did not produce a corneal injury and produced only mild conjunctivitis. No ocular effects were produced by a 1% solution.
In rabbits, measurements of corneal thickness were made prior to exposure, several times on the day following exposure, and at 24, 48, and 72 hr after the exposure. Exposures were by inhalation for 2 hr at 0.1, 1, 5, 10, 12, 15, 25, or 30 ppm LUPRAGEN N 205 (DMAEE). Concentration-related increases in corneal thickness in rabbits were observed immediately following the exposure at between 10 and 30 ppm of LUPRAGEN N 205 (DMAEE), with the thickness generally reaching a maximum at 3 hr postexposure.
Groups of six female rats were exposed to air saturated with the vapors of LUPRAGEN N 205 (DMAEE) for 8 hr. No deaths occurred. Lacrimation and excess conjunctival irritation were observed.

LUPRAGEN N 205 (Bis (2-dimethylaminoethyl) ether)’s production and use as a laboratory reagent and as a catalyst in the manufacturing of polyurethane foams may result in its release to the environment through various waste streams. If released to air, an estimated vapor pressure of 0.75 mm Hg at 25 °C indicates LUPRAGEN N 205 (Bis (2-dimethylaminoethyl) ether) will exist solely as a vapor in the atmosphere. Vapor-phase LUPRAGEN N 205 (Bis (2-dimethylaminoethyl) ether) will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 0.6 hrs. LUPRAGEN N 205 (Bis (2-dimethylaminoethyl) ether) does not contain chromophores that absorb at wavelengths >290 nm, and therefore is not expected to be susceptible to direct photolysis by sunlight. If released to soil, LUPRAGEN N 205 (Bis (2-dimethylaminoethyl) ether) is expected to have very high mobility based upon an estimated Koc of 13. However, the estimated pKa values of LUPRAGEN N 205 (Bis (2-dimethylaminoethyl) ether) are 8.14 and 9.21, indicating that this compound will exist almost entirely in the cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts. Volatilization from moist soil is not expected because the compound exists as a cation and cations do not volatilize. Utilizing the Japanese MITI test, 0% of the Theoretical BOD was reached in 4 weeks indicating that biodegradation is not a rapid environmental fate process. If released into water, LUPRAGEN N 205 (Bis (2-dimethylaminoethyl) ether) is not expected to adsorb to suspended solids and sediment based upon the estimated Koc. The pKa values indicate LUPRAGEN N 205 (Bis (2-dimethylaminoethyl) ether) will exist almost entirely in the cation form at pH values of 5 to 9 and therefore volatilization from water surfaces is not expected to be an important fate process. An estimated BCF of 3 suggests the potential for bioconcentration in aquatic organisms is low. Hydrolysis is not expected to be an important environmental fate process since this compound lacks functional groups that hydrolyze under environmental conditions. Occupational exposure to LUPRAGEN N 205 (Bis (2-dimethylaminoethyl) ether) may occur through inhalation and dermal contact with this compound at workplaces where LUPRAGEN N 205 (Bis (2-dimethylaminoethyl) ether) is produced or used.
LUPRAGEN N 205 (Bis (2-dimethylaminoethyl) ether)’s production and use as a laboratory reagent(1) and as a catalyst in the manufacturing of polyurethane foams(2) may result in its release to the environment through various waste streams(SRC).
Based on a classification scheme(1), an estimated Koc value of 13(SRC), determined from a structure estimation method(2), indicates that LUPRAGEN N 205 (Bis (2-dimethylaminoethyl) ether) is expected to have very high mobility in soil(SRC).

Une exposition aiguë / une application non occluse de 10 µL de LUPRAGEN N 205 (DMAEE) non dilué sur la peau de lapins a produit une nécrose locale marquée. Des lésions cutanées plus graves ont été produites lorsque le matériau a été maintenu sur la peau sous un pansement occlusif pendant 4 heures.
Exposition aiguë / LUPRAGEN N 205 (DMAEE) a été appliqué sur les yeux de lapins non dilué ou sous forme de solution aqueuse à 1%, 5% ou 15%. Lorsqu’il est administré non dilué, LUPRAGEN N 205 (DMAEE) a provoqué une lésion cornéenne étendue, une iritis, une grave irritation conjonctivale et une chimiose. Une solution à 15% n’a pas produit de lésion cornéenne et n’a produit qu’une légère conjonctivite. Aucun effet oculaire n’a été produit par une solution à 1%.
Chez les lapins, des mesures de l’épaisseur de la cornée ont été effectuées avant l’exposition, plusieurs fois le jour suivant l’exposition et 24, 48 et 72 heures après l’exposition.
