Oxalyl chloride Usage And Synthesis

Chemical Properties

colourless liquid with a pungent odour

Uses

Oxalyl Chloride is used in the preparation of cardiolipin analogs which induce peroxidase activity by Cytochrome C. It is also used in the preparation of fluorescent indicators for cytosolic calcium.

Production Methods

Oxalyl Chloride, ClCOCOCl, mol wt 126.9, is produced by the reaction of anhydrous oxalic acid and phosphorus pentachloride.

Reactions

Oxalyl Chloride vigorously reacts with water, alcohols, and amines, and is employed for the synthesis of agrochemicals, pharmaceuticals, and fine chemicals.

Safety Profile

Poison. Violently decomposed by water and alcohol. Severe irritant to skin, eyes, respiratory tract. Explodeson contact with dimethyl sulfoxide. Forms shock-sensitive explosive mixtures with potassium or with K-Na alloy. Will react with water or steam to
