Chemical Structure

5-Heptyl-1,3,4-oxadiazole-2(3H)-thione CAS 66473-10-7 chemical structure

Description

The molecular framework of 5-Heptyl-1,3,4-oxadiazole-2(3H)-thione (C9H16N2OS) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

5-Heptyl-1,3,4-oxadiazole-2(3H)-thione (CAS 66473-10-7) is a high-purity analytical reference standard with the molecular formula C9H16N2OS and a molecular weight of 200.30 g/mol.

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), 5-Heptyl-1,3,4-oxadiazole-2(3H)-thione 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.
