CATO supplies (2S,3S,4S,5R,6R)-3,4,5-trihydroxy-6-(((2R,3S,4R)-1,2,4-trihydroxy-5-oxopentan-3-yl)oxy)tetrahydro-2H-pyran-2-carboxylic acid (CAS 475598-94-8), a certified reference material (molecular formula C11H18O11, MW 326.25 g/mol) for analytical method development and quality control.
Structurally, (2S,3S,4S,5R,6R)-3,4,5-trihydroxy-6-(((2R,3S,4R)-1,2,4-trihydroxy-5-oxopentan-3-yl)oxy)tetrahydro-2H-pyran-2-carboxylic acid (C11H18O11) contains a carbohydrate-derived structure. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 326.25 g/mol, it falls into the moderately-high-molecular-weight range. 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.
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.
