The (phenylthio)acetate ion, also known as thiophenylacetic acid ion or S-phenyl ethanethiolate, is an organic compound with the chemical formula C8H7O-S. It is derived from the parent compound phenylacetic acid, where the hydroxyl group (-OH) is replaced by a thiol group (-SH). This ion is a conjugate base of the (phenylthio)acetic acid, which is an acidic compound with a pKa value of approximately 3.5. The (phenylthio)acetate ion is an important intermediate in the synthesis of various organic compounds, particularly in the preparation of thiophene derivatives and other sulfur-containing molecules. It is also used in the study of enzyme mechanisms and as a reagent in organic synthesis.

Check Digit Verification of cas no

The CAS Registry Mumber 4358-92-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,5 and 8 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4358-92:
(6*4)+(5*3)+(4*5)+(3*8)+(2*9)+(1*2)=103
103 % 10 = 3
So 4358-92-3 is a valid CAS Registry Number.

Micellar Effects upon the Hydrolysis of Activated Amides. Mechanistic Aspects

Cipiciani, Antonio,Linda, Paolo,Savelli, Gianfranco,Bunton, Clifford A.

, p. 5262 - 5267 (1983)

Reactions of OH- in water with N-acylpyrrole, -indole, and -carbazole (acyl = acetyl or benzoyl) are second order in OH- in 10-3 M NaOH and first order in more concentrated OH-, but reaction in micelles of cetyltrimethylammonium bromide (CTABr) is first order in micellar-bound OH- for both 10-3 and 0.05 M NaOH.Reactions are inhibited by anionic micelles of sodium lauryl sulfate (NaLS).The rate-surfactant profiles for rate enhancements in CTABr, and inhibition in NaLS, are analyzed in terms of the distribution of OH- and amide between aqueous and micellar pseudophases: second-order rate constants for attack of OH- upon amide are lower in the micellar pseudophase than in water.Micellar effects upon reaction of OH- with anilides have been analyzed, giving second-order rate constants in the micellar pseudophase which are very similar to those in water.
