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-1-naphthoyl chloride.
4-Bromo-1-naphthoyl chloride (CAS 87700-65-0), molecular formula C11H6BrClO and molecular weight 269.52 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-Bromo-1-naphthoyl chloride (C11H6BrClO) contains a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 269.52 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 4-Bromo-1-naphthoyl 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.
