Import Cbz-Amino Acids — Buy in Bulk from Supplier in China

Cbz-amino acids are N-carboxybenzyl-protected amino acid derivatives widely used as intermediates in peptide synthesis and pharmaceutical manufacturing. These compounds feature a Cbz protecting group that shields the amino function during chemical reactions, enabling selective modification of other functional groups. The supplier’s offering targets researchers and manufacturers requiring high-purity building blocks for drug development, bioconjugation, or nutraceutical formulations.

The product is typically supplied as a white to off-white crystalline powder, with purity levels often exceeding 98% as determined by HPLC analysis, a standard benchmark for pharmaceutical-grade amino acids. Common variants include Cbz-L-alanine, Cbz-L-phenylalanine, and Cbz-L-lysine, among others, each with distinct molecular weights and solubility profiles. Typical storage conditions require a dry, inert atmosphere at 2 - 8°C to prevent degradation, and the material is usually packaged in sealed containers under nitrogen.

Pharmaceutical companies, research institutions, and nutraceutical producers are the primary buyers, utilising Cbz-amino acids in the synthesis of peptides, APIs, and specialised supplements. Bulk supply is standard for industrial applications, with packaging options ranging from kilogram-scale drums to multi-ton orders. Confirm the supplier’s ability to provide custom synthesis or specific enantiomers, as well as their adherence to GMP or ISO standards for your project.

Ningbo Chemchen Bio-tech Co., Ltd is located in Zhenhai District, Ningbo, Zhejiang, China, with its registered address at No. 300-308 Zhenluo West Road, Luotuo Street. The company operates as an imported-tier supplier in the harbor trust tier, indicating a focus on international trade of biochemical products. While the supplier’s response rate is currently listed as 0.00, this may reflect temporary data gaps rather than operational limitations.

The supplier specialises in pharmaceutical intermediates, including protected amino acids, and serves clients in the pharmaceutical, biotechnology, and nutraceutical sectors. Their product portfolio aligns with the needs of researchers and manufacturers requiring high-purity chemical building blocks. Buyers should confirm the supplier’s current certifications, such as ISO or GMP, as well as their capacity for custom synthesis or large-scale production.
