Chemical Structure

Isoxazole-5-carbonitrile CAS 68776-59-0 chemical structure

Description

Owing to an amide group, a hydroxyl group, an ether linkage, Isoxazole-5-carbonitrile is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 94.07 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).

CATO supplies Isoxazole-5-carbonitrile (CAS 68776-59-0), a certified reference material (molecular formula C4H2N2O, MW 94.07 g/mol) for analytical method development and quality control.

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), Isoxazole-5-carbonitrile 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.
