Unnatural Amino Acids Process Development and Manufacturing

We are experts in producing a variety of unnatural amino acids including most challenging structures per our customers' specifications from kilo to metric ton scale. With our global quality standard, we develop robust process of amino acid products in superior quality with effective cost control.

α-Me-amino acids: Employ natural amino acid Alanine to design α-Me-amino acid derivatives. This type of methods can be applied to other natural amino acids (Leucine, Phenylalanine, etc.)

N-Me-amino acids: Develop the cyclization process to form the methylation by simply two steps

PG series: All protecting strategies (Boc, Fmoc, Cbz, Mtt, DDE, IVDDE) can be applied

α- and β- construction series: Develop enzyme catalyst techniques to construct selectable α- or β-site unnatural amino acids

NCA series: develop the process to well control the quality of NCAs

With the knowledge and synthetic skills of our experienced chemists , we also offer amino acid custom synthesis service. If your desired structure is not in this list, or you want a bulk order, we are happy to support.  For custom synthesis inquiry, we can synthesize up to kg at laboratory, and ton scale at our dedicated factory, please send your requests to, and we will respond shortly when we receive your custom synthesis inquiry.
