N-Nitrosodimethylamine | (CH3)2NN=O - PubChem
A method for quantitative estimation of the formation of N-nitrosodimethylamine (NDMA) in mice was developed. When 0.25 umole of aminopyrine and 0.25-2.0 umole of sodium nitrite were simultaneously administration orally to mice, the amt of NDMA formed in 20 min was 8.2-60.3 nmol. These values are equal to approximately 30-200 ug/kg of body wt which are nearly daily doses expected to cause …

What is the formula for N-nitrosodimethylamine ( NDMA )?
N-Nitrosodimethylamine ( NDMA ), also known as dimethylnitrosamine ( DMN ), is an organic compound with the formula (CH 3) 2 NNO. It is one of the simplest members of a large class of N-nitrosamines. It is a volatile yellow oil. NDMA has attracted wide attention as being highly hepatotoxic and a known carcinogen in laboratory animals.

What is the maximum concentration of NDMA in drinking water?
Groundwater near rocket launch sites often has high levels of NDMA. The United States Environmental Protection Agency (EPA) determined that the maximal admissible concentration of NDMA in drinking water is 7 ng/L. As of July 2020, the EPA has not set a regulatory maximal contaminant level (MCL) for drinking water.

What are the side effects of exposure to NDMA?
Exposure to high levels of NDMA may cause liver damage in humans (ATSDR 1999; HSDB 2013). Potential symptoms of overexposure include headache; fever; nausea; jaundice; vomiting; abdominal cramps; enlarged liver; reduced function of liver, kidneys and lungs; and dizziness (HSDB 2013; OSHA 2005).

How is NDMA used in the United States?
NDMA is not currently produced in pure form or commercially used in the United States, except for research purposes. It was formerly used in production of liquid rocket fuel, antioxidants, additives for lubricants and softeners for copolymers (ATSDR 1989; HSDB 2013).
