Chemical Structure

L-Norvaline, N-[(2S)-6,8-difluoro-1,2,3,4-tetrahydro-2-naphthalenyl]-, 1,1-dimethylethyl ester CAS 1309869-67-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 339.42 g/mol gives L-Norvaline, N-[(2S)-6,8-difluoro-1,2,3,4-tetrahydro-2-naphthalenyl]-, 1,1-dimethylethyl ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies L-Norvaline, N-[(2S)-6,8-difluoro-1,2,3,4-tetrahydro-2-naphthalenyl]-, 1,1-dimethylethyl ester (CAS 1309869-67-7), a certified reference material (molecular formula C19H27F2NO2, MW 339.42 g/mol) for analytical method development and quality control.

The molecular framework of L-Norvaline, N-[(2S)-6,8-difluoro-1,2,3,4-tetrahydro-2-naphthalenyl]-, 1,1-dimethylethyl ester (C19H27F2NO2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.

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.
