Chemical Structure
Description
(3-(Benzoyloxy)-2,4-dichlorophenyl)boronic acid (CAS 827299-99-0), molecular formula C13H9BCl2O4 and molecular weight 310.93 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (3-(Benzoyloxy)-2,4-dichlorophenyl)boronic acid (C13H9BCl2O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 8.5, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 310.93 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), (3-(Benzoyloxy)-2,4-dichlorophenyl)boronic acid 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.
