Chemical Structure

2,3,4,5,6-Pentachlorotoluene CAS 877-11-2 chemical structure

Description

Owing to chlorine substitution, an aromatic ring system, 2,3,4,5,6-Pentachlorotoluene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 264.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO supplies 2,3,4,5,6-Pentachlorotoluene (CAS 877-11-2), a certified reference material (molecular formula C7H3Cl5, MW 264.36 g/mol) for analytical method development and quality control.

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), 2,3,4,5,6-Pentachlorotoluene 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.
