General Description

(E,E)-[3-methyl-5-(2,6,6-trimethyl-1-cyclohexen-1-yl)penta-2,4-dienyl]triphenylphosphonium chloride is a synthetic chemical compound that belongs to the class of phosphonium salts. It is a complex molecule containing a phosphorus atom linked to three phenyl groups and a penta-2,4-dienyl group, which is further substituted with a 3-methyl-5-(2,6,6-trimethyl-1-cyclohexen-1-yl) moiety. (E,E)-[3-methyl-5-(2,6,6-trimethyl-1-cyclohexen-1-yl)penta-2,4-dienyl]triphenylphosphonium chloride has been used in research and industrial applications as a reactant in organic synthesis, particularly in the preparation of functionalized phosphonium salts and as a precursor in the production of pharmaceuticals, agrochemicals, and materials science. Furthermore, the chloride counterion in the molecule provides stability and solubility in polar solvents, making it suitable for various chemical reactions and applications.

Check Digit Verification of cas no

The CAS Registry Mumber 53282-28-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,2,8 and 2 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 53282-28:
(7*5)+(6*3)+(5*2)+(4*8)+(3*2)+(2*2)+(1*8)=113
113 % 10 = 3
So 53282-28-3 is a valid CAS Registry Number.

Preparation method of vitamin A ester intermediate C15 and vitamin A ester

-

Paragraph 0152-0157, (2020/08/18)

The invention provides a preparation method of a vitamin A ester intermediate C15 and vitamin A ester. The method comprises the following steps: carrying out a halogenation reaction and a cyclizationreaction on 3, 7-dimethyl-3-hydroxy-1, 6-octadiene as an initial raw material, carrying out a substitution reaction on the obtained product and triphenylphosphine or triester phosphite to prepare a corresponding Wittig reagent, carrying out a Wittig reaction on the Wittig reagent and 2-methyl-4-acetoxy-2-butenal, performing acidifying, hydrolyzing and acidifying the obtained product, and carryingout a substitution reaction on the hydrolyzed and acidified product and triphenylphosphine or triester phosphite to prepare C15. The vitamin A ester can be prepared by carrying out a Wittig reaction on the obtained C15 and 2-methyl-4-R3 substituent carbonyloxy-2-butenal. The method has the advantages of single reaction type, easy operation and realization of reaction conditions, safe and environment-friendly operation, simple post-treatment and low cost; and the reaction activity is strong, the reaction selectivity is high, the atom economy is high, and the target product yield and purity arehigh.

PROCESS FOR PREPARATION OF HIGHLY PURE ISOTRETINOIN

-

Page/Page column 4, (2008/12/08)

The present invention relates to a process for preparation of isotretinoin and more specifically, to a purification process for obtaining highly pure isotretinoin that is useful as a keratolytic agent, particularly useful for the treatment of acne. The process involves treating isotretinoin containing metal contamination and/or other impurities with a base in a suitable solvent to form a solution of isotretinoin, followed by adsorption, precipiation, and filtration or centrifugation
