Chemical Structure

2-oxo-1H,2H,3H-pyrido[2,3-b][1,4]thiazine-7-carboxylic acid hydrate CAS 1423024-87-6 chemical structure

Description

2-oxo-1H,2H,3H-pyrido[2,3-b][1,4]thiazine-7-carboxylic acid hydrate (CAS 1423024-87-6) is a high-purity analytical reference standard with the molecular formula C8H6N2O3SH2O and a molecular weight of 228.22 g/mol.

Based on its molecular formula C8H6N2O3SH2O, 2-oxo-1H,2H,3H-pyrido[2,3-b][1,4]thiazine-7-carboxylic acid hydrate contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 228.22 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
