Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,5-Dichloro-4-methylphenacyl bromide.
2,5-Dichloro-4-methylphenacyl bromide (CAS 1803836-64-7) is a high-purity analytical reference standard with the molecular formula C9H7BrCl2O and a molecular weight of 281.96 g/mol.
2,5-Dichloro-4-methylphenacyl bromide (C9H7BrCl2O) contains a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 2,5-Dichloro-4-methylphenacyl bromide 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.
