Chemical Structure
Description
The occurrence of 2-(2-Thienyl)benzothiazole is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-(2-Thienyl)benzothiazole (CAS 34243-38-4), a certified reference material (molecular formula C11H7NS2, MW 217.31 g/mol) for analytical method development and quality control.
Structurally, 2-(2-Thienyl)benzothiazole (C11H7NS2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 217.31 g/mol, it falls into the medium-molecular-weight range. 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-(2-Thienyl)benzothiazole 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.
