About HCTU, 98%

Vaqora Chemicals supplies HCTU, a peptide synthesis reagent registered under CAS number 330645-87-9 at a purity of 98%. Its molecular formula is C11H15ClF6N5OP and its molecular weight is 413.69 g/mol. The IUPAC name is [(5-chloro-3-oxidobenzotriazol-3-ium-1-yl)-(dimethylamino)methylidene]-dimethylazanium hexafluorophosphate.

In its supplied form it is white to almost white powder or crystals. Reported physical data include a melting point of above 185 °C. Store in a tightly closed container in a cool, dry and well-ventilated place. Under GHS it is labelled “Danger”, so handle it with suitable PPE and consult the SDS.

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

Standard pack sizes are 5 g, 25 g, 100 g and 1 kg, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
