Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-{[(4-fluorophenyl)methyl]sulfanyl}-5-[1-phenyl-5-(1H-pyrrol-1-yl)-1H-pyrazol-4-yl]-1,3,4-oxadiazole.
2-{[(4-fluorophenyl)methyl]sulfanyl}-5-[1-phenyl-5-(1H-pyrrol-1-yl)-1H-pyrazol-4-yl]-1,3,4-oxadiazole (CAS 956573-39-0), molecular formula C22H16FN5OS and molecular weight 417.46 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, fluorine substitution, 2-{[(4-fluorophenyl)methyl]sulfanyl}-5-[1-phenyl-5-(1H-pyrrol-1-yl)-1H-pyrazol-4-yl]-1,3,4-oxadiazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 417.46 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-fluorophenyl)methyl]sulfanyl}-5-[1-phenyl-5-(1H-pyrrol-1-yl)-1H-pyrazol-4-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.
