2-Bromo-8-chloro-2-fluoro-6-methoxy-3,4-dihydronaphthalen-1(2H)-one CAS 2874192-52-4 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 2-Bromo-8-chloro-2-fluoro-6-methoxy-3,4-dihydronaphthalen-1(2H)-one.

2-Bromo-8-chloro-2-fluoro-6-methoxy-3,4-dihydronaphthalen-1(2H)-one (CAS 2874192-52-4) is a high-purity analytical reference standard with the molecular formula C11H9BrClFO2 and a molecular weight of 307.54 g/mol.

Structurally, 2-Bromo-8-chloro-2-fluoro-6-methoxy-3,4-dihydronaphthalen-1(2H)-one (C11H9BrClFO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 307.54 g/mol, it falls into the moderately-high-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.

As a certified reference material (CRM), 2-Bromo-8-chloro-2-fluoro-6-methoxy-3,4-dihydronaphthalen-1(2H)-one 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.
