Chemical Structure
Description
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.
CATO supplies <I>S</I>-(5′-腺苷)-<I>L</I>-甲硫氨酸-(<I>S</I>-甲基-<SUP>13</SUP>C)氯盐 (CAS 74084-24-5), a certified reference material (molecular formula C14[13C]H23N6O5S HCl Cl, MW 471.35 g/mol) for analytical method development and quality control.
Structurally, <I>S</I>-(5′-腺苷)-<I>L</I>-甲硫氨酸-(<I>S</I>-甲基-<SUP>13</SUP>C)氯盐 (C14[13C]H23N6O5S HCl Cl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine 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 471.35 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.
