1-(4-Bromo-1-hydroxynaphthalen-2-yl)ethanone CAS 52220-64-1

Description

Compared with other compounds in its class, the molecular weight of 265.10 g/mol gives 1-(4-Bromo-1-hydroxynaphthalen-2-yl)ethanone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-(4-Bromo-1-hydroxynaphthalen-2-yl)ethanone (CAS 52220-64-1), molecular formula C12H9BrO2 and molecular weight 265.10 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1-(4-Bromo-1-hydroxynaphthalen-2-yl)ethanone (C12H9BrO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, 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 265.10 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 1-(4-Bromo-1-hydroxynaphthalen-2-yl)ethanone 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.
