Product Description
(R)-2-Methyl-CBS-oxazaborolidine is an organoboron Catalyst that is used in organic synthesis. This catalyst, developed by Itsuno and Elias James Corey, is generated by heating (R)-(+)-2-(diphenylhydroxymethyl) pyrrolidine along with trimethylboroxine or methylboronic acid. It is an excellent tool for the synthesis of alcohols in high enantiomeric ratio. Generally, 2-10 mol% of this catalyst is used along with borane-tetrahydrofuran (THF), borane-dimethylsulfide, borane-N,N-diethylaniline, or diborane as the borane source. Enantioselective reduction using chiral oxazaborolidine catalysts has been used in the synthesis of commercial drugs such as ezetimibe and aprepitant.
1> Cosmetic Raw Materials: Cosmetics is a variety of raw materials through a reasonable deployment of processing from the compound mixture. Cosmetics with a wide range of raw materials, different performance. According to the Raw Material properties and uses of cosmetics, can be divided into matrix materials and auxiliary raw materials in two categories. 2> Active Pharmaceutical Ingredients(API): API refers to the raw materials in the production of various types of preparations, which is the active ingredient in powder,crystal and paste for medicine use through chemical synthesis,plant extract, and preparations of biotechnology institute. 3> Fragrance And Spices: Spices are an important part of fine Chemicals, it is composed of natural spices, synthetic spices and single fragrance. 4> Organic Raw Material: Intermediates are also known as organic intermediates. The use of coal tar or petroleum products as raw materials to produce dyes, resins, additives, and other intermediates. 5> Chemicals Used In Paints: Paint, the traditional Chinese name is paint. So-called coating is coated on the surface of the object that be protected or be adornment, and with the continuous film coating to form strong adhesion. 6> Pharmaceutical Intermediates: The so-called pharmaceutical intermediates, refers to the production of pharmaceutical products in the process, the use of raw materials, materials, accessories and other intermediate products. 7> Agricultural Chemicals: Research and agriculture related chemical, including pesticide, plant growth regulator, fertilizer, compound fertilizer, herbicide etc. Product expansion
