Benzenesulfenyl chloride, 4-methyl-2-nitro-, also known as 2-nitro-4-methylbenzenesulfonyl chloride or 4-methyl-2-nitrophenylsulfonyl chloride, is an organic compound with the chemical formula C7H6ClNO3S. It is a yellow crystalline solid that is soluble in organic solvents. Benzenesulfenyl chloride, 4-methyl-2-nitro- is primarily used as an intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals. It is also employed as a reagent in organic synthesis, particularly in the preparation of sulfonamide derivatives. Due to its reactivity, it is essential to handle Benzenesulfenyl chloride, 4-methyl-2-nitro- with care, as it can be harmful if inhaled, ingested, or absorbed through the skin.

4288-90-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4288-90-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,8 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4288-90:
(6*4)+(5*2)+(4*8)+(3*8)+(2*9)+(1*0)=108
108 % 10 = 8
So 4288-90-8 is a valid CAS Registry Number.

Electrophilic cleavage of cyclopropanes. II. Concerning the effect of increasing electron demand upon the product-determining transition state in the reaction of 4-substituted-2-nitrobenzenesulphenyl chlorides and benzenesulphenyl chlorides with tetracyclo2,7.04,6>heptane....

Beaulieu, Pierre L.,Kabo, Ann,Garratt, Dennis G.

, p. 1014 - 1020 (2007/10/02)

The effect of increasing electron demand upon the product-determining transition state in the reaction of arenesulphenyl chlorides with tetracyclo2,7.04,6>heptane has been investigated.As the electron donating ability of the remote substituents on the phenyl ring of the sulphenyl chloride is varied from nitro to methoxy the relative proportion of adducts derived from edge-on attack is found to increase relative to that of adducts derived from corner attack.An ortho-nitro group was found to lead to a stabilizing interaction only in the case of 2,4-dinitrobenzenesulphenyl chloride.A mechanism involving the competition between the two conceptual modes of approach is suggested.
