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 3,5-dibromobenzoic acid chloride.
3,5-dibromobenzoic acid chloride (CAS 23950-59-6), molecular formula C7H3Br2ClO and molecular weight 298.36 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C7H3Br2ClO, 3,5-dibromobenzoic acid chloride contains a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 298.36 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 3,5-dibromobenzoic acid chloride 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.
