Beijing Chemsynlab Pharmaceutical Science & Technology Co. Ltd., focuses on R&D of pharmaceuticals and intermediates, especially on carbohydrate chemistry since founded in 2004 by Li Dr.,  Li Zhang. and Guo Dr.. They all have rich experimence on the synthesis of oligosaccharides and its derivatives. Beijing Chemsynlab offers the synthesis of carbohydrate compounds from milligram to kilogram scale. Beijing Chemsynlab has developed and diversified into many areas of carbohydrate research and synthesis by now. Many products involving carbohydrate building blocks can be supplied by us, 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. These can facilitate customers in their synthesizing work. Custom synthesis for carbohydrates and its derivatives or related compounds is indeed appreciated. At the same time we have the ability to meet the new challenges in the areas of carbohydrate chemistry to a great extent.
