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 N-((3R,4R,5S,6R)-4,5-dihydroxy-6-(hydroxymethyl)-2-oxotetrahydro-2H-pyran-3-yl)acetamide.
CATO supplies N-((3R,4R,5S,6R)-4,5-dihydroxy-6-(hydroxymethyl)-2-oxotetrahydro-2H-pyran-3-yl)acetamide (CAS 19026-22-3), a certified reference material (molecular formula C8H13NO6, MW 219.19 g/mol) for analytical method development and quality control.
Structurally, N-((3R,4R,5S,6R)-4,5-dihydroxy-6-(hydroxymethyl)-2-oxotetrahydro-2H-pyran-3-yl)acetamide (C8H13NO6) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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 219.19 g/mol, it falls into the medium-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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
