4,4'-Methylenebis(2-chloroaniline) (MOCA, MBOCA, bisamine) is a substance used as a curing agent in polyurethane production.[3] It is a suspected human carcinogen, with a current threshold limit value of 0.01 ppm in the industrial atmosphere. Animal studies have resulted in tumor growth in the liver, lung, and bladder.[1] Employee exposure is often monitored by measurement of urinary MOCA in free and/or conjugated form.[4]
It is a weak base with a slight odor and is reactive to active metals such as sodium, potassium, magnesium and zinc.[1]
