RECOMMENDATIONS FOR THE PROTECTION OF HUMAN HEALTH a) Acetonitrile and mixtures containing it should be clearly labelled with a warning of the toxicity of acetonitrile.

A safe production method for acetone cyanohydrin

Urinary acetonitrile was detectable for 4 days after dosing, whereas free and combined cyanide were detectable until 11 days, at which time the animals were sacrificed.

Acetonitrile is also used in biotechnology research as a solvent in the synthesis of DNA and peptide sequencing (Borman, 1990).

b) Comparative studies on the kinetics of cyanide formation from acetonitrile, as well as of conjugation to thiocyanate and its elimination, should be conducted.

Acetonitrile is also used as a starting material for the synthesis of many chemicals such as acetophenone, alpha-naphthyl acetic acid, thiamine and acetomidine (Hawley, 1971).

Laetrile (another name for amygdalin derived from apricot kernels), which was formerly used as an anticancer agent, releases cyanide upon metabolism. Bitter almonds and apricot pits containing cyanogenic glycosides are still sold in health food stores and over the Internet (Suchard et al., 1998). Other drugs, such as sodium nitroprusside, which is used as an antihypertensive and in congestive heart failure (Guiha et al., 1974; Tinker, 1976; Aitken et al., 1977; Schultz, 1984; Rindone & Sloane 1992), also liberate hydrogen cyanide in the body. In sodium nitroprusside, the CN moiety represents 44% by weight of the molecule. Some aliphatic nitriles that are widely used in the chemical industry — i.e., acetonitrile (IPCS, 1993), acrylonitrile (IARC, 1999), succinonitrile, and adiponitrile — also release cyanide upon metabolism (Willhite & Smith, 1981).

of many essential oils including neroli and bergamot oils

Acetonitrile has been used as a solvent for polymer spinning and casting because of the combination of high solubility and desirable intermediate volatility.
