Vaqora Chemicals supplies L-Thioproline, a peptide synthesis reagent registered under CAS number 34592-47-7 at a purity of 98%. Its molecular formula is C4H7NO2S and its molecular weight is 133.17 g/mol. Systematically, it is named (4R)-1,3-thiazolidine-4-carboxylic acid. It is also known as L-4-Thiazolidinecarboxylic acid or (R)-Thiazolidine-4-carboxylic acid.
In its supplied form it is a white to yellowish powder. Literature values give a melting point of 190-200 °C (dec.). 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.
It is commonly used for peptide coupling, solid-phase peptide synthesis, bioconjugation and protein and peptide research. Buyers come mainly from academic and industrial research and diagnostics and biotechnology.
Standard pack sizes are 10 g, 25 g, 100 g and 1 kg, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
