5-Isothiocyanatopicolinonitrile CAS 145255-18-1 chemical structure

Description

CATO supplies 5-Isothiocyanatopicolinonitrile (CAS 145255-18-1), a certified reference material (molecular formula C7H3N3S, MW 161.18 g/mol) for analytical method development and quality control.

Structurally, 5-Isothiocyanatopicolinonitrile (C7H3N3S) contains a nitrile group, sulfur-containing functionality, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 161.18 g/mol, it falls into the medium-molecular-weight range. 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.

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