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 GLYCINE:HCL, ETHYL ESTER (13C2, 98%; 15N, 98%).
GLYCINE:HCL, ETHYL ESTER (13C2, 98%; 15N, 98%) (CAS 221080-32-6) is a high-purity analytical reference standard with the molecular formula C2[13C]2H9[15N]O2 HCl and a molecular weight of 127.57 g/mol.
The molecular framework of GLYCINE:HCL, ETHYL ESTER (13C2, 98%; 15N, 98%) (C2[13C]2H9[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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
