Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(3-Methoxyphenyl)-5-(1-methyl-3-(trifluoromethyl)-1H-thieno[2,3-c]pyrazol-5-yl)-1,3,4-oxadiazole.
CATO supplies 2-(3-Methoxyphenyl)-5-(1-methyl-3-(trifluoromethyl)-1H-thieno[2,3-c]pyrazol-5-yl)-1,3,4-oxadiazole (CAS 338747-63-0), a certified reference material (molecular formula C16H11F3N4O2S, MW 380.34 g/mol) for analytical method development and quality control.
The molecular framework of 2-(3-Methoxyphenyl)-5-(1-methyl-3-(trifluoromethyl)-1H-thieno[2,3-c]pyrazol-5-yl)-1,3,4-oxadiazole (C16H11F3N4O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. 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).
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-(3-Methoxyphenyl)-5-(1-methyl-3-(trifluoromethyl)-1H-thieno[2,3-c]pyrazol-5-yl)-1,3,4-oxadiazole 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.
