R&D Strengths
Strong Academic Collaboration Strong Academic Collaboration

We maintain close research partnerships with leading institutions such as Wuhan University, Sichuan University, Chengdu University, and the Chengdu Institute of Organic Chemistry under the Chinese Academy of Sciences. These collaborations support ongoing innovation and technical development.

Solid Technical Achievements Solid Technical Achievements

Baishixing holds 15 invention patents and 16 utility model patents. Among these is the production process for disodium tyrosine phosphate, a technique currently developed and mastered exclusively by our team. We also pioneered bromine-free production methods for disodium tyrosine and orotic acid, addressing long-standing challenges in the domestic industry.

Product Innovation Focus Product Innovation Focus

We have developed three major product lines: amino acids, oligopeptides, and amino acid-based raw materials for cell culture media. More than 300 products have been successfully launched to meet diverse needs across pharmaceutical, biotech, and health-related sectors.

Manufacturing Capabilities

Our production capacity is supported by two specialized facilities. The Chengdu site operates four production lines focused on amino acid derivatives, while the Lanzhou facility runs six CGMP-compliant lines dedicated to protected amino acids and oligopeptides.

We are a manufacturer with two production facilities. One is located in Chengdu and focuses on amino acid derivatives, while the other is in Lanzhou, equipped with CGMP-compliant lines for protected amino acids and peptides.

Start by contacting our sales team with your product requirements. Once your needs are confirmed, we will provide a solution and issue a Proforma Invoice. Both parties will then proceed with contract confirmation before production and shipment.

We primarily accept T/T (telegraphic transfer) in advance. Payment terms may vary depending on the order amount, contract conditions, and customer status.

We can arrange delivery by air, sea, train, or multimodal transport depending on your destination and timeline.

Delivery times depend on the shipping method and destination. For air freight, delivery typically takes 3–7 days. Sea freight may range from 15 to 60 days depending on the region.
