Chemical Structure
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.
Thioproperazine-d3 Difumarate (CAS 1331638-03-9), molecular formula C22H27D3N4O2S2C4H4O4 and molecular weight 565.72 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C22H27D3N4O2S2C4H4O4, Thioproperazine-d3 Difumarate contains deuterium isotope labeling, a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 565.72 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 Thioproperazine-d3 Difumarate 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.
