Wellman Biosciences Co., Ltd. is a chemical and biotechnology company driven by the life sciences. Located in the Huanggang Chemical Industrial Park of Hubei Province, China, Wellman Biosciences occupies an area of 100,000 square meters with a construction area of 28,000 square meters for office, production workshop, and waste treatment facilities. Wellman Biosciences operates its own research and development center near Princeton in New Jersey, USA.

Innovative and highly developed production technologies are intrinsic to Wellman Biosciences range of services. The company is building the largest and most economical production base of high purity L-valine (over 1,000 tons per year), D-valine (500 tons per year), and their derivatives (such as Cbz, Boc, methyl ester, and Dane salts). Wellman Biosciences is the only manufacturer in the world with the expertise to produce L-valine and D-valine products that are free from contamination of other amino acids such as alanine, isoleucine and leucine. Compared with other products, Wellman's L-valine and D-valine product line offers utmost purity and is therefore extremely useful as a building block for the agricultural, biotechnological, and pharmaceutical industries.

Wellman Biosciences is continually expanding its scientific and technological base, assigning a high priority to advanced R&D as well as state-of-the–art plants and equipment to ensure environmentally safe and quality-focused production. As a result, the company is constructing the production facility to become one of the largest producers of L-2-aminobutyric acid (1,000 tons per year), a key starting material for the production of Levetiracetam and intermediates. As an expert producer of amino acids, other specialty amino acids such as L-norvaline and L-tert-leucine and D-phenylalanine, are produced as important intermediates of active pharmaceutical ingredients.

Creative thinking, dedicated staff and sound resources are the strengths on which Wellman Biosciences relies for further growth. Our employees are the key to success–they have extensive expertise in multidisciplinary project management and they are passionately committed to delivering sustainable value to their customers.
