Chemical Structure

Alpha,Alpha,Alpha,4-Tetrachlorotoluene CAS 5216-25-1 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies Alpha,Alpha,Alpha,4-Tetrachlorotoluene (CAS 5216-25-1), a certified reference material (molecular formula C7H4Cl4, MW 229.92 g/mol) for analytical method development and quality control.

Owing to chlorine substitution, an aromatic ring system, Alpha,Alpha,Alpha,4-Tetrachlorotoluene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 229.92 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

As a certified reference material (CRM), Alpha,Alpha,Alpha,4-Tetrachlorotoluene 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.
