3957-69-5 Usage
General Description
3-tert-butyl-4-hydroxy-5-methylphenyl thiocyanate, also known as irgasan, is a chemical compound commonly used as an antimicrobial agent in personal care products and plastics. It belongs to the family of organothiocyantes and is characterized by its phenolic structure and sulfur-containing thiocyanate group. Irgasan is effective in inhibiting the growth of bacteria and fungi, making it a valuable ingredient in products such as soaps, deodorants, and medical supplies. However, there are concerns about its potential toxicity and the development of antimicrobial resistance, leading to its restricted use in some regions. Overall, 3-tert-butyl-4-hydroxy-5-methylphenyl thiocyanate plays an important role in preserving the quality and safety of various consumer and healthcare products.
Check Digit Verification of cas no
The CAS Registry Mumber 3957-69-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,5 and 7 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 3957-69:
(6*3)+(5*9)+(4*5)+(3*7)+(2*6)+(1*9)=125
125 % 10 = 5
So 3957-69-5 is a valid CAS Registry Number.

S-(HYDROXYMETHYL) 4-HYDROXYPHENYL SULFIDES: SYNTHESIS AND SELECTED CHEMISTRY OF SOME STABLE HEMIMERCAPTALS
Pastor, Stephen D.,Odorisio, Paul A.,Ravichandran, Ramanathan
, p. 67 - 72 (2007/10/02)
The base-catalyzed reaction of 3,5-di-tert-butyl-4-hydroxybenzenethiol (1a), 3-tert-butyl-4-hydroxy-5-methylbenzenethiol (1b), and 4-hydroxybenzenethiol (1c) with formaldehyde gave the corresponding hemimercaptal derivatives 2a-c, respectively.The stable hemimercaptals 2a-c were characterized by IR, 1H NMR, 13C NMR, MS and elemental analysis.The ester of 2a with 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoic acid (3a) was prepared using triphenylphosphine and diethyl azodicarboxylate (Mitsunobu conditions).
