Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-{5-[(3-Methoxyphenyl)methylene]-4-oxo-2-thioxo-1,3-thiazolan-3-yl}dihydro-2,6(1H,3H)-pyridinedione.
CATO supplies 1-{5-[(3-Methoxyphenyl)methylene]-4-oxo-2-thioxo-1,3-thiazolan-3-yl}dihydro-2,6(1H,3H)-pyridinedione (CAS 477859-23-7), a certified reference material (molecular formula C16H14N2O4S2, MW 362.42 g/mol) for analytical method development and quality control.
The molecular framework of 1-{5-[(3-Methoxyphenyl)methylene]-4-oxo-2-thioxo-1,3-thiazolan-3-yl}dihydro-2,6(1H,3H)-pyridinedione (C16H14N2O4S2) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 manufactures 1-{5-[(3-Methoxyphenyl)methylene]-4-oxo-2-thioxo-1,3-thiazolan-3-yl}dihydro-2,6(1H,3H)-pyridinedione 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.
