Chemical Structure

(2S,3S,4R,5R,6S)-2-fluoro-6-methyltetrahydro-2H-pyran-3,4,5-triyl triacetate CAS 129864-97-7 chemical structure

Description

The occurrence of (2S,3S,4R,5R,6S)-2-fluoro-6-methyltetrahydro-2H-pyran-3,4,5-triyl triacetate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(2S,3S,4R,5R,6S)-2-fluoro-6-methyltetrahydro-2H-pyran-3,4,5-triyl triacetate (CAS 129864-97-7), molecular formula C12H17FO7 and molecular weight 292.26 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, (2S,3S,4R,5R,6S)-2-fluoro-6-methyltetrahydro-2H-pyran-3,4,5-triyl triacetate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 292.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
