Chemical Structure

7-Ethoxybenzo[d]thiazole-2(3H)-thione CAS 767583-07-3 chemical structure

Description

7-Ethoxybenzo[d]thiazole-2(3H)-thione (CAS 767583-07-3) is a high-purity analytical reference standard with the molecular formula C9H9NOS2 and a molecular weight of 211.30 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 7-Ethoxybenzo[d]thiazole-2(3H)-thione is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 211.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
