About TBTU, 99%
TBTU is a peptide synthesis reagent (Puriss grade) carrying the CAS registry number 125700-67-6, specified at 99% purity. Its molecular formula is C11H16BF4N5O and its molecular weight is 321.08 g/mol. Systematically, it is named [benzotriazol-1-yloxy(dimethylamino)methylidene]-dimethylazanium tetrafluoroborate. It is also known as TBTU Reagent or 2-(1H-benzotriazol-1-yl)-1.
It is supplied as white to off-white powder or crystals. Literature values give a melting point of 205 °C. Store in a tightly closed container in a cool, dry and well-ventilated place. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.
Key uses span peptide coupling, solid-phase peptide synthesis, bioconjugation and protein and peptide research. Typical end-use sectors are academic and industrial research and diagnostics and biotechnology.
Available in 5 g, 25 g, 100 g and 500 g packs, TBTU is dispatched with a Certificate of Analysis (COA) to destinations worldwide.
