Chemical Structure

2-acetylbenzothiazole CAS 1629-78-3 chemical structure

Description

2-acetylbenzothiazole (CAS 1629-78-3), molecular formula C9H15NOS and molecular weight 185.29 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C9H15NOS, 2-acetylbenzothiazole contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 185.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 2-acetylbenzothiazole 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.
