Chemical Structure
Description
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.
<SC>L</SC>-赖氨酸-2-<SUP>15</SUP>N 盐酸盐 (CAS 82783-00-4) is a high-purity analytical reference standard with the molecular formula C6H14N[15N]O2 HCl and a molecular weight of 182.65 g/mol.
The molecular framework of <SC>L</SC>-赖氨酸-2-<SUP>15</SUP>N 盐酸盐 (C6H14N[15N]O2 HCl) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
