2'-(4-(3-Chlorothiophen-2-yl)thiazol-2-yl)-5,5'-dimethyl-2-phenyl-1',2'-dihydro-2H,3'H-[3,4'-bipyrazol]-3'-one CAS 321385-48-2

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-(3-Chlorothiophen-2-yl)thiazol-2-yl)-5,5'-dimethyl-2-phenyl-1',2'-dihydro-2H,3'H-[3,4'-bipyrazol]-3'-one.

2'-(4-(3-Chlorothiophen-2-yl)thiazol-2-yl)-5,5'-dimethyl-2-phenyl-1',2'-dihydro-2H,3'H-[3,4'-bipyrazol]-3'-one (CAS 321385-48-2), molecular formula C21H16ClN5OS2 and molecular weight 453.97 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, 2'-(4-(3-Chlorothiophen-2-yl)thiazol-2-yl)-5,5'-dimethyl-2-phenyl-1',2'-dihydro-2H,3'H-[3,4'-bipyrazol]-3'-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 453.97 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 2'-(4-(3-Chlorothiophen-2-yl)thiazol-2-yl)-5,5'-dimethyl-2-phenyl-1',2'-dihydro-2H,3'H-[3,4'-bipyrazol]-3'-one 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.
