Chemical Structure
Description
The occurrence of 1-Oxo-2',3',5',6'-tetrahydrospiro[isochroman-3,4'-thiopyran]-4-carboxylic acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-Oxo-2',3',5',6'-tetrahydrospiro[isochroman-3,4'-thiopyran]-4-carboxylic acid (CAS 1263206-82-1) is a high-purity analytical reference standard with the molecular formula C14H14O4S and a molecular weight of 278.32 g/mol.
1-Oxo-2',3',5',6'-tetrahydrospiro[isochroman-3,4'-thiopyran]-4-carboxylic acid (C14H14O4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
