Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 210.25 g/mol gives 2-Amino-5,6-dimethoxybenzothiazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Amino-5,6-dimethoxybenzothiazole (CAS 6294-52-6), molecular formula C9H10N2O2S and molecular weight 210.25 g/mol, is a CATO reference standard with documented purity and traceability.
2-Amino-5,6-dimethoxybenzothiazole (C9H10N2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures 2-Amino-5,6-dimethoxybenzothiazole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
