Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4,5-Dichloro-2-hydrazinylbenzo[d]thiazole (CAS 872696-05-4) is a high-purity analytical reference standard with the molecular formula C7H5Cl2N3S and a molecular weight of 234.11 g/mol.
Owing to a nitrile group, sulfur-containing functionality, chlorine substitution, an aromatic ring system, 4,5-Dichloro-2-hydrazinylbenzo[d]thiazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 234.11 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).
As a certified reference material (CRM), 4,5-Dichloro-2-hydrazinylbenzo[d]thiazole 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.
