Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2S)-2-Amino-3,3-Dimethyl-5-Phenylpentanoic Acid.
CATO supplies (2S)-2-Amino-3,3-Dimethyl-5-Phenylpentanoic Acid (CAS 911448-55-0), a certified reference material (molecular formula C13H19NO2, MW 221.30 g/mol) for analytical method development and quality control.
The molecular framework of (2S)-2-Amino-3,3-Dimethyl-5-Phenylpentanoic Acid (C13H19NO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
