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 5-((4-Fluorophenyl)sulfinyl)-N-methyl-1,2,3-thiadiazole-4-carboxamide.
5-((4-Fluorophenyl)sulfinyl)-N-methyl-1,2,3-thiadiazole-4-carboxamide (CAS 339107-82-3), molecular formula C10H8FN3O2S2 and molecular weight 285.32 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, 5-((4-Fluorophenyl)sulfinyl)-N-methyl-1,2,3-thiadiazole-4-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 285.32 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), 5-((4-Fluorophenyl)sulfinyl)-N-methyl-1,2,3-thiadiazole-4-carboxamide 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.
