Uses
1-Naphthalenesulfonyl chloride has been used in the preparation of 5?-O-naphthaleneiulfonyldeoxyuridine and 1-sulfonylindazole derivatives. The derivatives of this compound is used for quantitative metabolome analysis New set of isotope reagents, 12C4-, 12C213C2-, and 13C4-5-diethylamino-naphthalene-1-sulfonyl chloride (DensCl), in combination with liquid chromatography Fourier-transform ion cyclotron resonance mass spectrometry (LC-FTICR-MS) is used for improved analysis of the amine- and phenol-containing submetabolome.
General Description
1-Naphthalenesulfonyl chloride undergoes desulfitative carbonylative Stille cross-coupling reaction with tinglucal derivative.
Purification Methods
If the IR indicates the presence of OH, then treat it with an equal weight of PCl5 and heat it at ca 100o for 2hours, cool and pour onto ice + H2O, stir well and filter off the solid. Wash the solid with cold H2O and dry the solid in a vacuum desiccator over P2O5 + solid KOH. Extract the solid with pet ether (b 40-60o), filter off any insoluble solid and cool. Collect the crystalline sulfonyl chloride and recrystallise it from dry Et2O, pet ether or *C6H6/pet ether. If large quantities are available, then it can be distilled under high vacuum. [Fierz-Davaid & Weissenbach Helv Chim Acta 3 2312 1920.] The sulfonamide crystallises from EtOH (m 150.5o) or H2O (m 153o). [Beilstein 11 H 175, 11 II 93, 11 IV 383.]
Check Digit Verification of cas no
The CAS Registry Mumber 85-46-1 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 5 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 85-46:
(4*8)+(3*5)+(2*4)+(1*6)=61
61 % 10 = 1
So 85-46-1 is a valid CAS Registry Number.

Facile synthesis of sulfonyl chlorides/bromides from sulfonyl hydrazides

A simple and rapid method for efficient synthesis of sulfonyl chlorides/bromides from sulfonyl hydrazide with NXS (X = Cl or Br) and late-stage conversion to several other functional groups was described. A variety of nucleophiles could be engaged in this transformation, thus permitting the synthesis of complex sulfonamides and sulfonates. In most cases, these reactions are highly selective, simple, and clean, affording products at excellent yields.

Phosphorus oxychloride efficiently promoted the synthesis of sulfonamides and sulfonic esters from thiols with hydrogen peroxide in the presence of Amberlite IRA-400 (OH-). This method has been applied to a variety of substrates including nucleophilic and sterically hindered amines, and also phenols with excellent yields of sulfonamides and sulfonic esters. In most cases these reactions are highly selective, simple, and clean, affording products in excellent yields and high purity.
