(Z)-2-(4-oxo-3,4-dihydro-2H-benzo[e][1,3]thiazin-2-ylidene)acetonitrile CAS 67431-58-7

Description

(Z)-2-(4-oxo-3,4-dihydro-2H-benzo[e][1,3]thiazin-2-ylidene)acetonitrile (CAS 67431-58-7), molecular formula C10H6N2OS and molecular weight 202.23 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (Z)-2-(4-oxo-3,4-dihydro-2H-benzo[e][1,3]thiazin-2-ylidene)acetonitrile (C10H6N2OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).

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), (Z)-2-(4-oxo-3,4-dihydro-2H-benzo[e][1,3]thiazin-2-ylidene)acetonitrile 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.
