Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-((2S,3R,4R,5R,6R)-2-(((2R,3S,4R,5R)-5-acetamido-1,2,4-trihydroxy-6-oxohexan-3-yl)oxy)-4,5-dihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)acetamide.
N-((2S,3R,4R,5R,6R)-2-(((2R,3S,4R,5R)-5-acetamido-1,2,4-trihydroxy-6-oxohexan-3-yl)oxy)-4,5-dihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)acetamide (CAS 136198-41-9), molecular formula C16H28N2O11 and molecular weight 424.40 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, N-((2S,3R,4R,5R,6R)-2-(((2R,3S,4R,5R)-5-acetamido-1,2,4-trihydroxy-6-oxohexan-3-yl)oxy)-4,5-dihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)acetamide (C16H28N2O11) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 424.40 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).
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.
As a certified reference material (CRM), N-((2S,3R,4R,5R,6R)-2-(((2R,3S,4R,5R)-5-acetamido-1,2,4-trihydroxy-6-oxohexan-3-yl)oxy)-4,5-dihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)acetamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
