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 (2S,3R,4S,5R,6R)-2-(4-Fluoro-2-nitrophenoxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol.
(2S,3R,4S,5R,6R)-2-(4-Fluoro-2-nitrophenoxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (CAS 694439-20-8), molecular formula C12H14FNO8 and molecular weight 319.24 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (2S,3R,4S,5R,6R)-2-(4-Fluoro-2-nitrophenoxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (C12H14FNO8) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 319.24 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
