Methyl (2S,3S,4S,5R,6R)-3,4,5,6-tetramethoxytetrahydro-2H-pyran-2-carboxylate CAS 31506-17-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl (2S,3S,4S,5R,6R)-3,4,5,6-tetramethoxytetrahydro-2H-pyran-2-carboxylate.

Methyl (2S,3S,4S,5R,6R)-3,4,5,6-tetramethoxytetrahydro-2H-pyran-2-carboxylate (CAS 31506-17-9), molecular formula C11H20O7 and molecular weight 264.27 g/mol, is a CATO reference standard with documented purity and traceability.

Methyl (2S,3S,4S,5R,6R)-3,4,5,6-tetramethoxytetrahydro-2H-pyran-2-carboxylate (C11H20O7) contains a carboxylic acid 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.

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

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
