Description
As a certified reference material (CRM), n-(4-Bromo-3-methylphenyl)-2-chloropropanamide 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.
n-(4-Bromo-3-methylphenyl)-2-chloropropanamide (CAS 1016746-86-3) is a high-purity analytical reference standard with the molecular formula C10H11BrClNO and a molecular weight of 276.56 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, n-(4-Bromo-3-methylphenyl)-2-chloropropanamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 276.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
