1225-13-4 Usage
General Description
MESO-2,3-DIPHENYLSUCCINIC ACID is a chemical compound that belongs to the class of organic compounds known as diphenylacetic acids. These are aromatic compounds containing a phenoxy group and a phenyl group bonded to the same acetic acid. It is used in the production of pharmaceuticals, agrochemicals, and dyestuffs. It is a white to off-white crystalline powder with a slightly unpleasant, acrid odor. It is insoluble in water but soluble in alcohol, chloroform, and ether and is considered safe when handled appropriately.
Check Digit Verification of cas no
The CAS Registry Mumber 1225-13-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,2 and 5 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1225-13:
(6*1)+(5*2)+(4*2)+(3*5)+(2*1)+(1*3)=44
44 % 10 = 4
So 1225-13-4 is a valid CAS Registry Number.

Convenient synthetic methods to C2 symmetric 3,4-diphenylpyrrolidines
Rao, Vutukuri Dharma,Periasamy, Mariappan
, p. 703 - 706 (2007/10/03)
Convenient methods of synthesis of racemic and optically pure 3,4- diphenylpyrrolidine derivatives, involving oxidative coupling of ethyl phenylacetate using TiCl4/Et3N and reduction of the dl-2,3-diphenylsuccinic acid or the corresponding cyclic imide with NaBH4/I2 reagent in crucial steps, are described.
Influence of β-arranged substituents in chiral seven-membered rhodium diphosphine rings on asymmetric hydrogenation of amino acid precursors
Krause, Hanswalter,Sailer, Cornelia
, p. 271 - 279 (2007/10/02)
Investigations concerning the optical induction in asymmetric hydrogenation reactions confirm the stereochemical control function of mono- and di-substituents in seven-membered chelate ring diphosphines, whereby the bulkiness of substituents in the backbone of the ligands is reflected in higher enantioselectivities.
