Chemical Structure
Description
CATO supplies (R)-2-Amino-3-(3,4-dimethoxyphenyl)-2-methylpropanoic acid hydrochloride (CAS 2503-41-5), a certified reference material (molecular formula C12H17NO4HCl, MW 275.73 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, (R)-2-Amino-3-(3,4-dimethoxyphenyl)-2-methylpropanoic acid hydrochloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 275.73 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
CATO manufactures (R)-2-Amino-3-(3,4-dimethoxyphenyl)-2-methylpropanoic acid hydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
