Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5,7-Dichloro-2,3-dihydrobenzofuran-3-acetic Acid.

5,7-Dichloro-2,3-dihydrobenzofuran-3-acetic Acid (CAS 2070896-36-3) is a high-purity analytical reference standard with the molecular formula C10H8Cl2O3 and a molecular weight of 247.07 g/mol.

Structurally, 5,7-Dichloro-2,3-dihydrobenzofuran-3-acetic Acid (C10H8Cl2O3) 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 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 247.07 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), 5,7-Dichloro-2,3-dihydrobenzofuran-3-acetic 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.
