4630-95-9 Usage
Description
Prifinium bromide is a synthetic antispasmodic drug with parasympatholytic properties. It is a quartenary anticholinergic agent, which means it can block the action of acetylcholine, a neurotransmitter responsible for various bodily functions, including muscle contractions and gland secretions.
Uses
Used in Pharmaceutical Industry:
Prifinium bromide is used as a quartenary anticholinergic agent for its antispasmodic and parasympatholytic effects. It is particularly useful in treating conditions that involve excessive muscle contractions, such as gastrointestinal spasms, biliary colic, and peptic ulcer disease. By blocking the action of acetylcholine, prifinium bromide helps to relax the smooth muscles and alleviate symptoms associated with these conditions.
Check Digit Verification of cas no
The CAS Registry Mumber 4630-95-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,3 and 0 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4630-95:
(6*4)+(5*6)+(4*3)+(3*0)+(2*9)+(1*5)=89
89 % 10 = 9
So 4630-95-9 is a valid CAS Registry Number.

Highly regioselective intramolecular aminolysis of 3,4-epoxy amines has been achieved. Key features of this reaction are (1) chemoselective activation of epoxides in the presence of unprotected aliphatic amines in the same molecules by a La(OTf)3 catalyst and (2) excellent regioselectivity for anti-Baldwin 5-endo-tet cyclization. This reaction affords 3-hydroxy-2-alkylpyrrolidines stereospecifically in high yields. DFT calculations revealed that the regioselectivity might be attributed to distortion energies of epoxy amine substrates. The use of this reaction was demonstrated by the first enantioselective synthesis of an antispasmodic agent prifinium bromide.
