Chemical Properties

yellow crystalline powder

Uses

2,4-Dinitrobenzenesulfonyl chloride was used to protect primary amines. It was used as starting reagent in the synthesis of tert-butyl 2-[(2,4-dinitrophenyl) sulfonyl]amino acetate.

General Description

2,4-Dinitrobenzenesulfonyl chloride causes the sulfonation of glycosylamines to yield N-glycosyl-2,4-dinitrobenzenesulfonamides.

Purification Methods

Crystallise the sulfonyl chloride from *benzene or *benzene/pet ether. [Beilstein 11 H 78, 11 IV 214.]

Check Digit Verification of cas no

The CAS Registry Mumber 1656-44-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,5 and 6 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1656-44:
(6*1)+(5*6)+(4*5)+(3*6)+(2*4)+(1*4)=86
86 % 10 = 6
So 1656-44-6 is a valid CAS Registry Number.
