Our R&D headquarters located in Shanghai and every factory owns the separate R&D laboratory independently.

Capabilities:
 Scheme design & optimization
 R&D (multi-steps Reaction)
 Kilo-lab 
 Commercial Production

Advantage:
 In China, the capacity of suppliers can mainly be divided into 2 different styles. Like those labs in SIOC, Chem Partner, Corner Chem, they are strong at those complex chemicals for combination chemistry at grams to kilograms quantity level. But they have no experience in commercial production at all. On the other hand, most of Chinese factory have a good experience in commercial production, but weak at multi-steps reactions. Only few large companies can handle both well such as Hison and Pharmatech. However, although Hwasun is not those large companies in China, we have rich experience in R&D and up-scaling, especially in Custom synthesis/Contract manufacture/Toll Manufacture.

Technologies:
 We are strong at below reactions:
   - Amidation
   - Acylation
   - Alkylation (Alkyl Sulfates, etc.)
   - Bromination (HBr, HBr/H2O2, Br2, NBS, etc.)
   - Chlorination (POCl3, Cl2, PCl3/5, SOCl2, etc.)
   - Cyanation (NaCN, KFeCN6, CuCN, PTC/Tetrabutylammonium Cyanide,etc)
   - Friedel-Crafts Reactions
   - Grignard Reactions
   - Hydroboration
   - Hydrogenation
   - Iodination Reduction
   - Mannich Reactions
   - Michael Addition
   - Nitration
   - Oxidation (H2O2, KMnO4, K2CrO7, Se/SeO2, air/catalyst, etc.)
   - Pd-catalyzed Carbonylation Catalysis
   - Phase Transfer catalysis
   - Phosgenation
   - Reduction (NaBH4, NaH, Zinc Powder, Raney Nickel, Red-Al,  etc.)
   - Sandmeyer Reactions
   - Suzuki Couplings

Reaction Range:
 Temperature range: -60°C~200°C
 Pressure limits: 0~30 atms
