93-92-5 Usage
Description
α-Methylbenzyl acetate has an intensive green odor suggestive of
gardenia with a bitter, acrid taste, interesting on dilution. May be
prepared by acetylation of methyl phenyl carbinol; from benzaldehyde by reacting with magnesium methyl bromide and subsequent acetylation; from 1-bromoethylbenzene and silver acetate in
acetic acid.

Flammability and Explosibility
Nonflammable
Metabolism
Although no published data exist on the metabolism of methylphenylcarbinyl acetate, it is likely that hydrolysis to the carbinol and acetic acid is the initial step. Williams (1959) reports studies in which 50% of a dose of (±)-methylphenylcarbinol given to rabbits was excreted as the glucuronide in the urine within 24 hr. There was some evidence of oxidation and demethylation, as mandelic and hippuric acids were found in the urine. Previously, El Masry, Smith
Check Digit Verification of cas no
The CAS Registry Mumber 93-92-5 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 9 and 3 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 93-92:
(4*9)+(3*3)+(2*9)+(1*2)=65
65 % 10 = 5
So 93-92-5 is a valid CAS Registry Number.

The invention provides a method for synthesizing styrallyl acetate from acetophenone, which comprises the following steps: reacting acetophenone with ketene under the catalysis of organic acid to obtain styrene acetate, and hydrogenating styrene acetate to obtain styrallyl acetate. The method is novel in synthetic route, the raw materials acetophenone and ketene are cheap and easy to obtain, the synthetic route is short, the yield is high, no equivalent acetic acid byproduct is produced, and the method has an obvious cost advantage.

Trimethylsilyl esters, AcOTMS, BzOTMS, TCAOTMS, etc., are inexpensive and chemically stable reagents that pose a negligible environmental hazard. Such compounds prove to serve as efficient dualpurpose reagents to respectively achieve acylation and trimethylsilylation of alcohols under acidic or basic conditions. Herein, a detailed study on protection of various substrates and new methodological investigations is described.
