Chemical Structure

(S)-2-(Methylamino)-2-phenylacetic acid hydrochloride CAS 4418-82-0 chemical structure

Description

The occurrence of (S)-2-(Methylamino)-2-phenylacetic acid hydrochloride is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(S)-2-(Methylamino)-2-phenylacetic acid hydrochloride (CAS 4418-82-0), molecular formula C9H11NO2HCl and molecular weight 201.65 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (S)-2-(Methylamino)-2-phenylacetic acid hydrochloride (C9H11NO2HCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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.

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.
