Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Bromo-N-(1-methyl-1H-pyrazol-3-yl)benzamide.
4-Bromo-N-(1-methyl-1H-pyrazol-3-yl)benzamide (CAS 879728-56-0), molecular formula C11H10BrN3O and molecular weight 280.12 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-Bromo-N-(1-methyl-1H-pyrazol-3-yl)benzamide (C11H10BrN3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 280.12 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-Bromo-N-(1-methyl-1H-pyrazol-3-yl)benzamide 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.
