4,4'-Methylenebis(2-chloroaniline) (also known as MOCA, MBOCA, and bisamine) is a substance used as a curing agent in polyurethane production. MOCA is an aromatic amine which is structurally similar to benzidine, a known human bladder has been shown to cause hepatomas in mice and rats, lung and mammary carcinomas in rats and bladder cancer in : faint, amine-like.

The DuPont Chambers Works in Deepwater, N.J., was a major producer of two carcinogens (beta-naphthylamine and benzidine) and two suspected bladder carcinogens (ortho-toluidine and 4,4'-methylenebis [2-chloroaniline]).

Hazard classification and labelling. The ‘Hazard classification and labelling’ section shows the hazards of a substance through a standardised system of statements and pictograms, as has been established under CLP (Classification Labelling and Packaging) Regulation. The CLP Regulation makes sure that the hazards presented by chemicals are clearly communicated to workers and consumers in. The chemical properties of 4,4'- Methylenebis (2-Chloroaniline) indicate that about 43% will enter the water, 28% aquatic sediments, and 30% terrestrial soil. The concentration of 4,4'-Methylenebis (2-Chloroaniline) found in fish tissues is expected to be somewhat higher than the average concentration of 4,4'-Methylenebis (2-Chloroaniline) in. 2-Chlorobenzenamine. Molecular Weight: O-chloroaniline is a clear amber liquid with an amine odor. Occurs in both alpha and beta forms. (NTP, ) from CAMEO Chemicals. Expand this section. 2 Names and Identifiers.

The rigid polyurethane foams are good thermal insulators, which find applications in all freezers and refrigerators, as well as in buildings. It is also used as an industrial strength adhesive, which is available to end consumers as various high-strength.
