Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(4-Oxo-5-((1-phenyl-3-(thiophen-2-yl)-1H-pyrazol-4-yl)methylene)-2-thioxothiazolidin-3-yl)acetic acid.
2-(4-Oxo-5-((1-phenyl-3-(thiophen-2-yl)-1H-pyrazol-4-yl)methylene)-2-thioxothiazolidin-3-yl)acetic acid (CAS 623934-95-2) is a high-purity analytical reference standard with the molecular formula C19H13N3O3S3 and a molecular weight of 427.52 g/mol.
The molecular framework of 2-(4-Oxo-5-((1-phenyl-3-(thiophen-2-yl)-1H-pyrazol-4-yl)methylene)-2-thioxothiazolidin-3-yl)acetic acid (C19H13N3O3S3) is characterized by a steroid 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. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-(4-Oxo-5-((1-phenyl-3-(thiophen-2-yl)-1H-pyrazol-4-yl)methylene)-2-thioxothiazolidin-3-yl)acetic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
