Chemical Structure

Chloridazon-Desphenyl CAS 6339-19-1 chemical structure

Description

As a certified reference material (CRM), Chloridazon-Desphenyl 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.

Chloridazon-Desphenyl (CAS 6339-19-1) is a high-purity analytical reference standard with the molecular formula C4H4ClN3O and a molecular weight of 145.55 g/mol.

Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Chloridazon-Desphenyl is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 145.55 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.
