Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

5-Fluoro-4-sulfanylidene-1,2,3,4-tetrahydropyrimidin-2-one (CAS 671-41-0), molecular formula C4H3FN2OS and molecular weight 146.14 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, 5-Fluoro-4-sulfanylidene-1,2,3,4-tetrahydropyrimidin-2-one is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 146.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

CATO manufactures 5-Fluoro-4-sulfanylidene-1,2,3,4-tetrahydropyrimidin-2-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
