Description

Compared with other compounds in its class, the molecular weight of 220.31 g/mol gives (R)-2-Amino-3-methyl-N-((S)-1-phenylethyl)butanamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(R)-2-Amino-3-methyl-N-((S)-1-phenylethyl)butanamide (CAS 781608-99-9) is a high-purity analytical reference standard with the molecular formula C13H20N2O and a molecular weight of 220.31 g/mol.

The molecular framework of (R)-2-Amino-3-methyl-N-((S)-1-phenylethyl)butanamide (C13H20N2O) 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 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-methyl-N-((S)-1-phenylethyl)butanamide 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.
