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 2-Chlorotoluene.
CATO supplies 2-Chlorotoluene (CAS 95-49-8), a certified reference material (molecular formula C7H7Cl, MW 126.58 g/mol) for analytical method development and quality control.
Owing to chlorine substitution, an aromatic ring system, 2-Chlorotoluene is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 126.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-Chlorotoluene 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.
