Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Bromo-2-chloro-5-fluorobenzoylchloride.
4-Bromo-2-chloro-5-fluorobenzoylchloride (CAS 203302-93-6) is a high-purity analytical reference standard with the molecular formula C7H2BrCl2FO and a molecular weight of 271.90 g/mol.
Owing to a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution, an aromatic ring system, 4-Bromo-2-chloro-5-fluorobenzoylchloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 271.90 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
