Naphtho[2,1-d]thiazol-2(3H)-one CAS 17931-24-7

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, Naphtho[2,1-d]thiazol-2(3H)-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 201.24 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).

Naphtho[2,1-d]thiazol-2(3H)-one (CAS 17931-24-7) is a high-purity analytical reference standard with the molecular formula C11H7NOS and a molecular weight of 201.24 g/mol.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), Naphtho[2,1-d]thiazol-2(3H)-one 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.
