4338-64-1 Usage
General Description
2-(1-methylnonyl)phenol, also known as nonylphenol, is a chemical compound commonly used in the production of industrial and commercial products such as detergents, pesticides, and plastics. It is classified as an endocrine disruptor, with studies showing it can interfere with hormonal balance in both animals and humans. Nonylphenol is also known to persist in the environment, where it can accumulate in the food chain and pose a risk to aquatic organisms. Due to its potential environmental and health impacts, nonylphenol has been subject to restrictions and bans in various regions, with efforts to find safer alternative chemicals in its place.
Check Digit Verification of cas no
The CAS Registry Mumber 4338-64-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,3 and 8 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4338-64:
(6*4)+(5*3)+(4*3)+(3*8)+(2*6)+(1*4)=91
91 % 10 = 1
So 4338-64-1 is a valid CAS Registry Number.

Alkylation of Phenol by 1-Dodecene and 1-Decanol. A Literature Correction
Campbell, Curt B.,Onopchenko, Anatoli,Santilli, Donald S.
, p. 3665 - 3669 (2007/10/02)
A recent literature report that 1-dodecene reacts with phenol in the presence of sulfated zirconium oxide (superacid), or 1-dodecanol with phenol in the presence of H-Mordenite (zeolite), to afford mostly para-substituted alkylphenols has been shown to be incorrect.The product with zirconium is a mixture of ortho/para isomers (ca. 50-65/50-35), and not the exclusive para isomer as reported.The major product in the case of zeolite catalysis is the o-alkylphenol, with a high degree of end attachment, and not the predominantly claimed para isomers.The selectivity obtained with H-Mordenite during alkylation of phenol differs from the a lkylation of alkylbenzenes and anisole, and is best explained on the basis of a surface catalysis phenomenon.
