Uses
Used in Chemical Synthesis:
2,4-Dinitrobenzenesulfonyl chloride is used as a reagent in the synthesis of various organic compounds. Its ability to undergo nucleophilic substitution reactions makes it a valuable intermediate in the preparation of sulfonamide derivatives and other related compounds.
Used in the Protection of Primary Amines:
In organic synthesis, primary amines can be protected using 2,4-dinitrobenzenesulfonyl chloride. This protection is achieved by converting the amine group into a more stable and unreactive form, which can be later deprotected to regenerate the original amine. This is particularly useful in multi-step synthesis processes where the amine group needs to be preserved from unwanted side reactions.
Used in the Synthesis of tert-Butyl 2-[(2,4-Dinitrophenyl) Sulfonyl]Amino Acetate:
2,4-Dinitrobenzenesulfonyl chloride serves as a starting reagent in the synthesis of tert-butyl 2-[(2,4-dinitrophenyl) sulfonyl]amino acetate, a compound that may have potential applications in pharmaceutical or chemical research.
Used in the Sulfonation of Glycosylamines:
2,4-Dinitrobenzenesulfonyl chloride is utilized in the sulfonation of glycosylamines, resulting in the formation of N-glycosyl-2,4-dinitrobenzenesulfonamides. This reaction is important in the synthesis of various glycoconjugates and may have applications in the development of glycobiology-related compounds.
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.
