1,3-Benzenedisulfonyl Chloride Usage And Synthesis

Chemical Properties

Light Brown Solid

Uses

1,3-Benzenedisulfonyl chloride is used as a pharmaceutical intermediates. The compound is used to produce1,3-benzenedisulfonohydrazide.

Production Methods

Manufactured from m-benzenedisulfonic acid and phosphorus pentachloride or from benzenesulfochloride andchlorosulfuric acid.

General Description

Benzene-1,3-disulfonyl chloride (BDD) or 1,3-benzenedisulfonyl chloride is dichloride of 1,3-benzenedisulfonic acid. It is a colorless (white) crystalline solid with a melting point of 59-62 °C. It is soluble in common organic solvents. Compounds are sensitive to moisture and react in water; therefore, they should be stored in dry conditions. It has corrosive properties and can cause severe skin burns and eye damage.

Purification Methods

Crystallise it from CHCl3 (EtOH free, by passing through an alumina column) or *C6H6/pet ether and dry it at 20mm pressure. [Beilstein 11 IV 553.]
