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 Ethyl 4-bromo-3,5-dichlorobenzoate.
Ethyl 4-bromo-3,5-dichlorobenzoate (CAS 1239741-87-7), molecular formula C9H7BrCl2O2 and molecular weight 297.96 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Ethyl 4-bromo-3,5-dichlorobenzoate (C9H7BrCl2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 297.96 g/mol, it falls into the medium-molecular-weight range. 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.
