Chemical Structure

2,3-Dihydrobenzothiazole CAS 4433-52-7 chemical structure

Description

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.

CATO supplies 2,3-Dihydrobenzothiazole (CAS 4433-52-7), a certified reference material (molecular formula C7H7NS, MW 137.20 g/mol) for analytical method development and quality control.

Owing to a nitrile group, sulfur-containing functionality, an aromatic ring system, 2,3-Dihydrobenzothiazole is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 137.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

As a certified reference material (CRM), 2,3-Dihydrobenzothiazole 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.
