Chemical Structure

2,5-Dimethoxybenzothiazole CAS 855464-94-7 chemical structure

Description

2,5-Dimethoxybenzothiazole (CAS 855464-94-7), molecular formula C9H9NO2S and molecular weight 195.24 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2,5-Dimethoxybenzothiazole (C9H9NO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 195.24 g/mol, it falls into the medium-molecular-weight range. 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.

As a certified reference material (CRM), 2,5-Dimethoxybenzothiazole 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.
