Peptide Synthesis & Amino Acids
Peptide synthesis is a solid-phase synthetic sequence, generally proceeding from the C-terminus (carboxyl terminus) to the N-terminus (amino terminus). It is also an intermediate product of protein hydrolysis. Howei provides over 5000 high-quality peptides, amino acids, and related protein products.
High-purity Biochemical Reagents
He provides high-purity biochemical reagents with a purity of ≥99.99%, which can be used in atomic absorption spectroscopy, precision analysis, and scientific research, where extremely high purity is required.
Building Blocks
Synthetic building blocks are functional molecular units with specific reactivity properties that can participate in the synthesis of various compounds as structural modules. They provide predictable reaction sites and connection modes, and enable the construction of complex molecular structures through modular combination.
Chemical Synthesis
We offer chemical synthesis products that transform simple substances into complex ones through chemical reactions. From stock reagents to specialized catalysts and building blocks, we have the right products to shorten your synthetic routes. Our product range is extensive, including coupling, halogenation, Grignard reagents, oxidation, protection, deprotection, reduction, organoaluminum, and organosilicon reagents.
