Chemical Structure
Description
As a certified reference material (CRM), 4-(3-Methoxycarbonylphenyl)benzoic 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.
CATO supplies 4-(3-Methoxycarbonylphenyl)benzoic acid (CAS 281232-91-5), a certified reference material (molecular formula C15H12O4, MW 256.25 g/mol) for analytical method development and quality control.
Structurally, 4-(3-Methoxycarbonylphenyl)benzoic acid (C15H12O4) contains a flavonoid core, a hydroxyl group, an ether linkage. 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 256.25 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.
