32315-10-9 Usage

Chemical Properties

White solid

Uses

An efficient carbonylating agent for liquid and solid-phase aza-peptide synthesis.

Purification Methods

It is a good solid substitute for phosgene (using a third mol per mol). Crystallise it from pet ether (b 60-80o), wash it with anhydrous cold Et2O, de-gas it at 200mm then dry at 0.1mm (over H2SO4). It has IR: max 900 and 1900 cm-1 . It is a lachrymator, is TOXIC and should be handled with gloves and in an efficient fume hood. [Hales et al.
