Advanced ChemTech is a multi-kilogram producer of Fmoc and Boc protected amino acids. Our experience includes the production of hundred kilo batches to very high quality standards. By stringently refining our manufacturing processes, we minimize impurities that can diminish yields and purities in the finished peptide product. Our quality assurance and testing standards ensure our customers receive the highest quality products, documented by the Certificate of Analysis that accompanies all shipments. If any product is in stock for more than two years, it is thoroughly retested for degradation and a new Certificate of Analysis is produced.
