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.
CATO supplies 2,6-Bis(4-chlorophenyl)pyrrolo[3,4-e][1,3]thiazine-5,7(6H,7aH)-dione (CAS 337920-14-6), a certified reference material (molecular formula C18H10Cl2N2O2S, MW 389.26 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 2,6-Bis(4-chlorophenyl)pyrrolo[3,4-e][1,3]thiazine-5,7(6H,7aH)-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 389.26 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 2,6-Bis(4-chlorophenyl)pyrrolo[3,4-e][1,3]thiazine-5,7(6H,7aH)-dione 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.
