Chemical Structure

L-Phenylalanine-13C9,15N CAS 878339-23-2 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.

L-Phenylalanine-13C9,15N (CAS 878339-23-2) is a high-purity analytical reference standard with the molecular formula [13C]9H11[15N]O2 and a molecular weight of 175.12 g/mol.

The molecular framework of L-Phenylalanine-13C9,15N ([13C]9H11[15N]O2) is characterized by an organic framework. 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
