α-Monodeutero propanesulfonic acid methyl ester is a chemical compound with the molecular formula C3H7D2O3S. It is a derivative of propanesulfonic acid, where one hydrogen atom is replaced by a deuterium atom (an isotope of hydrogen with one proton and one neutron). α-monodeutero propanesulfonic acid methyl ester is an ester, formed by the reaction of propanesulfonic acid with methanol, resulting in the methyl ester. It is a colorless liquid with a strong, pungent odor and is soluble in water and organic solvents. α-Monodeutero propanesulfonic acid methyl ester has potential applications in various fields, including pharmaceuticals, as a chiral auxiliary in asymmetric synthesis, and as a reagent in organic chemistry. Its deuterium labeling makes it useful for studying reaction mechanisms and kinetic isotope effects, as well as for use in nuclear magnetic resonance (NMR) spectroscopy.

Check Digit Verification of cas no

The CAS Registry Mumber 10307-22-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,3,0 and 7 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 10307-22:
(7*1)+(6*0)+(5*3)+(4*0)+(3*7)+(2*2)+(1*2)=49
49 % 10 = 9
So 10307-22-9 is a valid CAS Registry Number.

ALKANESULFONYLATION REACTIONS. I. CHARACTERISTICS OF THE ALKANESULFONYLATION OF PHENOL-d1 AND METHANOL-d1 CATALYZED BY TERTIARY AMINES

Skrypnik, Yu. G.,Bezrodnyi, V. P.

, p. 511 - 515 (2007/10/02)

The products from alkanesulfonylation of phenol-d1 and methanol-d1 catalyzed by tertiary amines, which occurs in at least three competing directions (nucleophilic and general base catalysis and a sulfene mechanism), were investigated.The degree of realization of the sulfene mechanism was determined from the content of the ester-d1, and its dependence on the structure of the catalysis, the substrate, the reagent, and the nature of the solvent was investigated.It was shown that the fraction of the ester-d1 decreases with decrease in the basicity and steric accessibility of the tertiary amine.Investigation of the effect of the structure of the sulfonyl chloride shows that the fraction of the sulfene mechanism decreases with decrease in the acidity of the α-protons and their steric accessibility.It was shown that the most favorable conditions for realization of the sulfene mechanism are created in benzene.
