Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Bromo-N-(5-methyl-1,3,4-thiadiazol-2(3h)-ylidene)furan-2-carboxamide.
5-Bromo-N-(5-methyl-1,3,4-thiadiazol-2(3h)-ylidene)furan-2-carboxamide (CAS 312592-85-1), molecular formula C8H6BrN3O2S and molecular weight 288.12 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 5-Bromo-N-(5-methyl-1,3,4-thiadiazol-2(3h)-ylidene)furan-2-carboxamide (C8H6BrN3O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 288.12 g/mol, it falls into the medium-molecular-weight range. 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), 5-Bromo-N-(5-methyl-1,3,4-thiadiazol-2(3h)-ylidene)furan-2-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.
