81201-84-5 L-Serine-1-13C L-(l-13C)Serine L-(1-13C)Serine CAS 81201-84-5

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 81201-84-5 L-Serine-1-13C L-(l-13C)Serine L-(1-13C)Serine (CAS 81201-84-5), a certified reference material (molecular formula C2[13C]H7NO3, MW 106.09 g/mol) for analytical method development and quality control.

81201-84-5 L-Serine-1-13C L-(l-13C)Serine L-(1-13C)Serine (C2[13C]H7NO3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
