2311-91-3 Usage

General Description

Perphthalic acid is a carboxylic acid with the chemical formula C8H4O5. It is a white crystalline solid that is soluble in water and organic solvents. Perphthalic acid is primarily used in the production of plasticizers, as well as in the synthesis of dyes and pigments. It is also utilized as an intermediate for the production of other chemicals and as a catalyst in various chemical reactions. Perphthalic acid is often preferred over other similar compounds due to its high melting point and stability, making it a valuable component in the chemical industry. However, it is important to handle perphthalic acid with care, as it is corrosive and can cause irritation to the skin and eyes.

Check Digit Verification of cas no

The CAS Registry Mumber 2311-91-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,1 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2311-91:
(6*2)+(5*3)+(4*1)+(3*1)+(2*9)+(1*1)=53
53 % 10 = 3
So 2311-91-3 is a valid CAS Registry Number.

Selective deoxygenation of allylic alcohol: Stereocontrolled synthesis of lavandulol

Kim, Hee Jin,Su, Liang,Jung, Heejung,Koo, Sangho

supporting information; experimental part, p. 2682 - 2685 (2011/06/26)

Selective deoxygenation of allylic alcohol can be successfully carried out by the formation of alkoxyalkyl ether (EE or MOM), followed by Pd(dppe)Cl 2-catalyzed reduction with LiBHEt3. (+)-S-Lavandulol has been efficiently synthesized by the application of this protocol to the diol derived from the Pb(OAc)4-promoted oxidative ring-opening of (-)-R-carvone. This deoxygenation method is general and selective for allylic alcohols.

-

Page 44; 45, (2010/02/07)

The present invention describes substituted 3-Aminoalkoxyindoles, as compounds of the general formula (I), its stereoisomers, its radioisotopes, its geometric forms, its N-oxides, its polymorphs, its pharmaceutically acceptable salts, its pharmaceutically acceptable solvates, its useful bioactive metabolites and any suitable combination of the above. The invention also discloses the processes for preparing such compounds of the general formula (I), its stereoisomers, its radioisotopes, its geometric forms, its N-oxides, its polymorphs, its pharmaceutically acceptable salts, its pharmaceutically acceptable solvates, its useful bio-active metabolites and also includes any suitable combination of the above. Further described are various methods of administering these compounds of general formula (I), i.e. pharmaceutically acceptable dosage forms, their composition and their use in either therapy or diagnosis.
