Chemical Structure

L-Phenylalanine-15N CAS 29700-34-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 166.18 g/mol gives L-Phenylalanine-15N distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies L-Phenylalanine-15N (CAS 29700-34-3), a certified reference material (molecular formula C9H11[15N]O2, MW 166.18 g/mol) for analytical method development and quality control.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, L-Phenylalanine-15N is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 166.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

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.
