Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Bromo-3-chloro-5-nitrobenzonitrile.
CATO supplies 2-Bromo-3-chloro-5-nitrobenzonitrile (CAS 1426805-54-0), a certified reference material (molecular formula C7H2BrClN2O2, MW 261.46 g/mol) for analytical method development and quality control.
Structurally, 2-Bromo-3-chloro-5-nitrobenzonitrile (C7H2BrClN2O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system. 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 261.46 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), 2-Bromo-3-chloro-5-nitrobenzonitrile 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.
