Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

3-Nitrophenacyl bromide 2-bromo-3'-nitroacetophenone 3'-nitrophenacyl bromide 2-bromo-1-(3-nitro-phenyl)-ethanone alpha-bromo-3'-nitroacetophenone a-bromo-3-nitroacetophenone 3'-nitro-2-bromo acetophenone 2-bromo-1-(3-nitrophenyl)ethanone 3-nitrophenacylbromide m-nitrophenacyl bromide a-bromo-m-nitroacetophenone 2227-64-7 (CAS 2227-64-7), molecular formula C8H12BrNO3 and molecular weight 250.09 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, 3-Nitrophenacyl bromide 2-bromo-3'-nitroacetophenone 3'-nitrophenacyl bromide 2-bromo-1-(3-nitro-phenyl)-ethanone alpha-bromo-3'-nitroacetophenone a-bromo-3-nitroacetophenone 3'-nitro-2-bromo acetophenone 2-bromo-1-(3-nitrophenyl)ethanone 3-nitrophenacylbromide m-nitrophenacyl bromide a-bromo-m-nitroacetophenone 2227-64-7 is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 250.09 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).

As a certified reference material (CRM), 3-Nitrophenacyl bromide 2-bromo-3'-nitroacetophenone 3'-nitrophenacyl bromide 2-bromo-1-(3-nitro-phenyl)-ethanone alpha-bromo-3'-nitroacetophenone a-bromo-3-nitroacetophenone 3'-nitro-2-bromo acetophenone 2-bromo-1-(3-nitrophenyl)ethanone 3-nitrophenacylbromide m-nitrophenacyl bromide a-bromo-m-nitroacetophenone 2227-64-7 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.
