Chemical Structure

2-Chlorobenzotrichloride CAS 2136-89-2 chemical structure

Description

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.

CATO supplies 2-Chlorobenzotrichloride (CAS 2136-89-2), a certified reference material (molecular formula C7H4Cl4, MW 229.92 g/mol) for analytical method development and quality control.

Structurally, 2-Chlorobenzotrichloride (C7H4Cl4) contains chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 229.92 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), 2-Chlorobenzotrichloride 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.
