Chemical Structure

4-Acetoxy-2-bromobenzophenone CAS 890099-44-2 chemical structure

Description

The occurrence of 4-Acetoxy-2-bromobenzophenone is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4-Acetoxy-2-bromobenzophenone (CAS 890099-44-2), a certified reference material (molecular formula C15H11BrO3, MW 319.15 g/mol) for analytical method development and quality control.

Structurally, 4-Acetoxy-2-bromobenzophenone (C15H11BrO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 319.15 g/mol, it falls into the moderately-high-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), 4-Acetoxy-2-bromobenzophenone 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.
