Thiotepa

About Thiotepa

Thiotepa is a high-purity reference standard of Thiotepa carrying the CAS registry number 52-24-4. With the molecular formula C6H12N3PS, it has a molar mass of 189.22 g/mol. Systematically, it is named tris(aziridin-1-yl)-sulfanylidene-lambda5-phosphane. Alternative names: Triethylenethiophosphoramide and Thiophosphamide.

It is supplied as a solid. Store the standard in its sealed vial, protected from light and moisture, and follow the storage condition printed on the COA. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

As a reference sample of Thiotepa, it is used for identification, assay and impurity-profiling work during analytical method development, validation (AMV) and routine QC. Typical end-use sectors are pharmaceutical manufacturing and academic and industrial research.

Standard pack sizes are 10 mg, 25 mg, 50 mg and 100 mg, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
