Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 259.73 g/mol gives (2S,3R)-3-Amino-2-(4-methoxybenzyl)butanoic acid hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (2S,3R)-3-Amino-2-(4-methoxybenzyl)butanoic acid hydrochloride (CAS 1263094-13-8), a certified reference material (molecular formula C12H17NO3HCl, MW 259.73 g/mol) for analytical method development and quality control.
The molecular framework of (2S,3R)-3-Amino-2-(4-methoxybenzyl)butanoic acid hydrochloride (C12H17NO3HCl) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
As a certified reference material (CRM), (2S,3R)-3-Amino-2-(4-methoxybenzyl)butanoic acid hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
