1951-12-8 Usage

General Description

3-Chlorobutyric acid, also known as β-chlorobutyric acid, is a chemical compound with the molecular formula C4H7ClO2. It is a colorless liquid with a pungent odor, and it is used in organic synthesis and as an intermediate in the production of pharmaceuticals and agrochemicals. It is also a precursor to the production of γ-butyrolactone, which is used as a solvent, an intermediate in the production of polymers, and as a precursor to various chemicals. 3-Chlorobutyric acid is classified as a hazardous chemical and should be handled with care due to its corrosive properties and potential health hazards if not used properly.

Check Digit Verification of cas no

The CAS Registry Mumber 1951-12-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,5 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1951-12:
(6*1)+(5*9)+(4*5)+(3*1)+(2*1)+(1*2)=78
78 % 10 = 8
So 1951-12-8 is a valid CAS Registry Number.

HYDROCHLORINATION OF ELECTRON-DEFICIENT ALKENES

-

Page/Page column 5, (2012/07/31)

The present invention pertains to a method for the hydrochlorination of electron deficient alkenes, particularly alkenes having the functional groups COOH, CONH2, and CN. Specific alkenes discussed include acrylic acid, crotonic acid, methacrylic acid, acrylonitrile, acrylamide, and methacrylonitrile. The alkene is combined with a primary or secondary alcohol (e.g., isopropanol) and an acid chloride (e.g., acetyl chloride) under conditions suitable to chlorinate the alkene. Products formed by the invention include 3-chorosubstituted carbonyl compounds such as 3-chlorpropionic acid (3-CPA), 3-chloropropionamide (3-CPAD), and 3-chloropropionitrile among other products.

AN IMPROVED SYNTHESIS OF HEXAMETHYLPHENALENE

The synthesis of 1,3,4,6,7,9-hexamethylphenalene (2) has been improved from 15 steps to a four step procedure.The overall yield has been increased from an estimated 5percent to 45percent.Key steps in the synthesis are the reaction of 3,5-dimethylbenzylmagnesium chloride with 2,4-pentanedioato lithium in THF to make 5-(3,5-dimethylphenyl)-4-methyl-4-hydroxy-2-pentanone (5) and the Lewis acid acylation-alkation of 1,3,6,8-tetramethylnaphthalene using 3-chlorobutanoic chloride in hexane with sonicaton to make 1,3,4,6,7,9-hexamethyl-phenalane (2).
