Beijing Chemsynlab Pharmaceutical Science & Technology Co., Ltd. ( China (Mainland))

Beijing Chemsynlab Pharmaceutical Science & Technology Co. Ltd. is dedicated to R&D of pharmaceuticals and intermediates, especially on carbohydrate chemistry. Utill now it has developed and diversified into many areas of carbohydrate research and synthesis. It is founded in 2004 by Li Dr., Li Zhang. and Guo Dr. who all have rich experimence on the synthesis of oligosaccharides and its derivatives. Most of the other workers have a bachelor or above degree.

Beijing Chemsynlab offers the synthesis of carbohydrate compounds from milligram to kilogram scale such as actived sugar donors including trichloroacetimidates, thioglycosides, acetylglycosyl halides and phosphates, glycals, sugar anhydrides, deoxy derivatives, amino sugars, uronic acid derivatives, alditols, glycosides and oligosaccharides, and so on for example: D-Glucaric acid with cas registry number of 87-73-0, alpha-D-Methylglucoside with cas registry number of 97-30-3, D-(+)-Cellobiose with cas registry number of 133-99-3, Cytarabine with cas registry number of 147-94-4, Erythritol with cas registry number of 149-32-6. At the same time, the company has the ability to meet the new challenges in the areas of carbohydrate chemistry to a great extent.

To indentify the structures of the intermediates or final products, Beijing Chemsynlab is equiped with many instruments such as NMR (400MHz, 1H, 13C, 1H-1HCOSY, HMQC, HMBC etc.), MS (APCI), IR. Besides this, HPLC and GC are also utilized to guarantee the quality of the compounds. The purity of the substances is on average between 97-99 % (HPLC). In addition, Chemical abstract database from internet are sci-finder and belstain. Full text database include ACS, Elsevier, willey and so on.
