Chemical Structure

Thiabendazole-5-hydroxy CAS 948-71-0 chemical structure

Description

As a certified reference material (CRM), Thiabendazole-5-hydroxy 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.

Thiabendazole-5-hydroxy (CAS 948-71-0), molecular formula C10H7N3OS and molecular weight 217.25 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, Thiabendazole-5-hydroxy is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 217.25 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.
