33657-49-7 Usage
Chemical Properties
Colorless to Almost colorless clear liquid.
Uses
clevidipine incorporates a methoxymethyl ester, a function that is readily cleaved to the corresponding acid by serum esterases. The actual experimental details in patents describe the preparation of this compound by simple alkylation of the monoester with chloromethyl butyrate.
Check Digit Verification of cas no
The CAS Registry Mumber 33657-49-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,6,5 and 7 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 33657-49:
(7*3)+(6*3)+(5*6)+(4*5)+(3*7)+(2*4)+(1*9)=127
127 % 10 = 7
So 33657-49-7 is a valid CAS Registry Number.

Chlorination of Esters. I. Chlorination of Methyl Esters of Propanoic, Butanoic, Pentanoic and Hexanoic Acids. The Isomer Distribution of Monochloro Esters Formed
Korhonen, Ilpo O.O.,Korvola, Jorma N.J.
, p. 139 - 142 (2007/10/02)
The chlorination of methyl ester with chlorine in the liquid and vapor phase and with sulfuryl chloride in the liquid phase has been investigated.The chlorination yields all possible monochloro esters isomers with the 2-chloro isomer in the smallest amount.The products were identified by NMR and mass spectrometry.The isomer distribution and mass spectra of products were studied in detail.
