Chemical Structure

2-Methoxy-5-methyl-6H-1,3-thiazine CAS 89996-48-5 chemical structure

Description

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

CATO supplies 2-Methoxy-5-methyl-6H-1,3-thiazine (CAS 89996-48-5), a certified reference material (molecular formula C6H9NOS, MW 143.21 g/mol) for analytical method development and quality control.

Structurally, 2-Methoxy-5-methyl-6H-1,3-thiazine (C6H9NOS) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 143.21 g/mol, it falls into the low-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).

CATO manufactures 2-Methoxy-5-methyl-6H-1,3-thiazine 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.
