Chemical Structure

Chlorohydroquinone CAS 615-67-8 chemical structure

Description

CATO supplies Chlorohydroquinone (CAS 615-67-8), a certified reference material (molecular formula C6H5ClO2, MW 144.56 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, Chlorohydroquinone is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 144.56 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.

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), Chlorohydroquinone 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.
