3639-21-2 Usage
Chemical Properties
white crystalline powder or needles
Uses
2-Ethyl-2-hydroxybutyric acid was used as internal standard during quantification of medium-chain-length bacterial poly(3-hydroxyalkanoate) by gas chromatography. It was used as ligand to study the effect of anionic and cationic surfactants on kinetics of electron transfer reaction from organic sulfides to [CrV(ehba)2]- (ehba=2-ethyl-2-hydroxy butyric acid).
General Description
2-Ethyl-2-hydroxybutyric acid forms 99mTc complexes.
Check Digit Verification of cas no
The CAS Registry Mumber 3639-21-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,3 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3639-21:
(6*3)+(5*6)+(4*3)+(3*9)+(2*2)+(1*1)=92
92 % 10 = 2
So 3639-21-2 is a valid CAS Registry Number.

One-flask preparation of symmetrical ketones and 1,2-diketones from esters
Olah,Wu
, p. 1177 - 1179 (2007/10/02)
A convenient one-flask preparation of a series of symmetrical 1,2-diketones from esters is reported using sodium metal induced acyloin condensation followed by reaction with thionyl chloride. Symmetrical monoketones were obtained when after initial acyloin condensation, the reaction mixture is oxidized with aqueous sodium bromate and then reacted with thionyl chloride. Preparative aspects, the scope of the reaction, and the suggested mechanism are discussed.
