(2R)-2-pentylbutanedioic acid, also known as (2R)-2-amethylpentanedioic acid, is a chiral organic compound with the molecular formula C9H16O4. It is a dicarboxylic acid, meaning it contains two carboxylic acid groups (-COOH) separated by a methylene group (-CH2-). The compound has a 2-pentyl substituent attached to the central carbon atom, which is in the R configuration. This chiral center imparts optical activity to the molecule, meaning it can rotate plane-polarized light. (2R)-2-pentylbutanedioic acid is a white crystalline solid and is used in the synthesis of various pharmaceuticals and other organic compounds. Its unique structure and properties make it an important building block in the development of new drugs and materials.

3975-91-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3975-91-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,7 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3975-91:
(6*3)+(5*9)+(4*7)+(3*5)+(2*9)+(1*1)=125
125 % 10 = 5
So 3975-91-5 is a valid CAS Registry Number.

Matlystatins, new inhibitors of type IV collagenases from Actinomadura atramentaria. IV. Synthesis and structure-activity relationships of matlystatin B and its stereoisomers

Tamaki,Kurihara,Oikawa,Tanzawa,Sugimura

, p. 1481 - 1492 (2007/10/02)

The first total synthesis of matlystatin B (1a), a low molecular weight inhibitor of type IV collagenases, was accomplished, and its absolute configuration was unambiguously determined. Furthermore, ten stereoisomers of 1a were synthesized, and the inhibi

ASYMMETRIC INDUCTION IN THE CYCLOADDITION REACTION OF DICHLOROKETENE WITH CHIRAL ENOL ETHERS. A VERSATILE APPROACH TO OPTICALLY ACTIVE CYCLOPENTENONE DERIVATIVES.

Greene, Andrew E.,Charbonnier, Florence

, p. 5525 - 5528 (2007/10/02)

Significant asymmetric induction has been observed in the cycloaddition reaction of dichloroketene with chiral enol ethers.The resultant diastereomeric cyclobutanones have been converted to synthetically useful α-chlorocyclopentenones in optically active form.
