α-Butyl-α-hydroxy phenyl methyl ester, also known as 4-hydroxy-3-methoxybenzyl butyrate, is an organic compound with the chemical formula C12H16O4. It is a derivative of vanillin, a naturally occurring organic compound found in vanilla beans, and is characterized by its pleasant aroma. This ester is formed by the esterification of 4-hydroxy-3-methoxybenzaldehyde (a vanillin derivative) with butyric acid. It is used as a synthetic flavoring agent in the food and beverage industry, as well as in the production of perfumes and cosmetics, due to its ability to mimic the scent of natural vanilla. The compound is also of interest in chemical research for its potential applications in the synthesis of other organic compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 97690-16-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,6,9 and 0 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 97690-16:
(7*9)+(6*7)+(5*6)+(4*9)+(3*0)+(2*1)+(1*6)=179
179 % 10 = 9
So 97690-16-9 is a valid CAS Registry Number.

ASYMMETRIC ALKYLATION OF AN Α-KETO ESTER WITH CHIRAL LITHIUM ALKOXY-TRIBUTYLALUMINATES

Abenhafn, D.,Boireau, G.,Sabourault, B.

, p. 3043 - 3046 (1980)

Lithium tetrabutylaluminate modified by either (-)-N-methylephedrine or Darvon alcohol (+)-(2S, 3R)-4-dimethylamino-3-methyl-1,2-diphenyl-2-butanol readily reacts with phenylglyoxylic acid methyl ester to give the expected α-butyl α-hydroxy ester with a good chemical yield and an optical yield of 43percent when Darvon alcohol is used.
