4,5-Difluoro-2-(propan-2-yloxy)benzoic acid CAS 1782612-50-3 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 4,5-Difluoro-2-(propan-2-yloxy)benzoic acid.

4,5-Difluoro-2-(propan-2-yloxy)benzoic acid (CAS 1782612-50-3) is a high-purity analytical reference standard with the molecular formula C10H10F2O3 and a molecular weight of 216.18 g/mol.

Structurally, 4,5-Difluoro-2-(propan-2-yloxy)benzoic acid (C10H10F2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 216.18 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), 4,5-Difluoro-2-(propan-2-yloxy)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.
