Chemical Structure
Description
As a certified reference material (CRM), 5-(4-Chlorophenoxy)isobenzofuran-1,3-dione 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 5-(4-Chlorophenoxy)isobenzofuran-1,3-dione (CAS 63196-10-1), a certified reference material (molecular formula C14H7ClO4, MW 274.66 g/mol) for analytical method development and quality control.
The molecular framework of 5-(4-Chlorophenoxy)isobenzofuran-1,3-dione (C14H7ClO4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
