Chemical Structure

1,2,3-Trichloro-5-(3,4-dichlorophenoxy)benzene CAS 94339-59-0 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 1,2,3-Trichloro-5-(3,4-dichlorophenoxy)benzene.

1,2,3-Trichloro-5-(3,4-dichlorophenoxy)benzene (CAS 94339-59-0) is a high-purity analytical reference standard with the molecular formula C12H5Cl5O and a molecular weight of 342.43 g/mol.

The molecular framework of 1,2,3-Trichloro-5-(3,4-dichlorophenoxy)benzene (C12H5Cl5O) is characterized by a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring 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.

As a certified reference material (CRM), 1,2,3-Trichloro-5-(3,4-dichlorophenoxy)benzene 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.
