About TBTU, AR

Listed under CAS 125700-67-6, TBTU is a peptide synthesis reagent available from Vaqora Chemicals (AR grade). Formula C11H16BF4N5O, molecular weight 321.08 g/mol. Systematically, it is named [benzotriazol-1-yloxy(dimethylamino)methylidene]-dimethylazanium tetrafluoroborate. It is also known as 2-(1H-benzotriazol-1-yl)-1 or KTB-1066-PI.

Store sealed in a dry, well-ventilated location away from incompatible materials. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

It is commonly used for peptide coupling, solid-phase peptide synthesis and bioconjugation. Buyers come mainly from academic and industrial research and diagnostics and biotechnology.

Standard pack sizes are 25 g, 100 g and 500 g, and every batch ships with a Certificate of Analysis (COA) and we export worldwide. A Safety Data Sheet (SDS) and technical specifications are available on request.
