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 1-Bromo-4-(bromomethyl)-5-chloro-2-fluorobenzene.
1-Bromo-4-(bromomethyl)-5-chloro-2-fluorobenzene (CAS 1355636-63-3), molecular formula C7H4Br2ClF and molecular weight 302.37 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to fluorine/chlorine/bromine substitution, an aromatic ring system, 1-Bromo-4-(bromomethyl)-5-chloro-2-fluorobenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 302.37 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.
As a certified reference material (CRM), 1-Bromo-4-(bromomethyl)-5-chloro-2-fluorobenzene 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.
