Description

CATO supplies <I>N</I>-acetyl-<SC>D</SC>-neuraminic acid-1,2,3-<SUP>13</SUP>C<SUB>3</SUB> (CAS 1172608-56-8), a certified reference material (molecular formula C8[13C]3H19NO9, MW 312.25 g/mol) for analytical method development and quality control.

Structurally, <I>N</I>-acetyl-<SC>D</SC>-neuraminic acid-1,2,3-<SUP>13</SUP>C<SUB>3</SUB> (C8[13C]3H19NO9) contains a carbohydrate-derived structure, an amide group. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 312.25 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
