5-Methyl-3-phenyl-4-isoxazolylisothiocyanate CAS 306934-97-4

Description

As a certified reference material (CRM), 5-Methyl-3-phenyl-4-isoxazolylisothiocyanate 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.

5-Methyl-3-phenyl-4-isoxazolylisothiocyanate (CAS 306934-97-4) is a high-purity analytical reference standard with the molecular formula C11H8N2OS and a molecular weight of 216.26 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 5-Methyl-3-phenyl-4-isoxazolylisothiocyanate is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 216.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
