5-hydroxy-2-(4-tolyl)isoindole-1,3-dione is a complex organic compound with the molecular formula C16H11NO3. It is a derivative of isoindole, which is a heterocyclic aromatic compound consisting of a benzene ring fused to a pyrrolidine-2,3-dione ring. The compound features a hydroxyl group (-OH) at the 5-position, a tolyl group (a methyl-substituted phenyl group) at the 2-position, and two carbonyl groups (C=O) at the 1 and 3 positions. This specific arrangement of functional groups gives the molecule unique chemical and physical properties, making it potentially useful in various applications, such as pharmaceuticals or materials science. However, further research and characterization are needed to fully understand its potential applications and properties.

Check Digit Verification of cas no

The CAS Registry Mumber 3975-49-3 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, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 3975-49:
(6*3)+(5*9)+(4*7)+(3*5)+(2*4)+(1*9)=123
123 % 10 = 3
So 3975-49-3 is a valid CAS Registry Number.

Tetsuhashi, Masashi,Ishikawa, Minoru,Hashimoto, Mariko,Hashimoto, Yuichi,Aoyama, Hiroshi

experimental part, p. 5323 - 5338 (2010/09/15)

A novel series of tryptase inhibitors with a N-phenylphthalimide skeleton structurally derived from thalidomide (1) has been developed. Structure-activity relationship studies led to a potent and selective tryptase inhibitor, 2-(4-cyanophenyl)isoindole-1,3-dione-5-yl 3-(2-aminopyridin-5-yl)propanoate (7), with the IC50 value of 78 nM.
