Chemical Structure

71261-64-8 DL-Alanine-15N 2-(15N)azanylpropanoic acid CAS 71261-64-8 chemical structure

Description

The molecular framework of 71261-64-8 DL-Alanine-15N 2-(15N)azanylpropanoic acid (C3H7[15N]O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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.

71261-64-8 DL-Alanine-15N 2-(15N)azanylpropanoic acid (CAS 71261-64-8) is a high-purity analytical reference standard with the molecular formula C3H7[15N]O2 and a molecular weight of 90.09 g/mol.
