(R)-4-([1,1'-Biphenyl]-4-yl)-3-((tert-butoxycarbonyl)amino)butanoic acid CAS 2411591-20-1

Description

The molecular framework of (R)-4-([1,1'-Biphenyl]-4-yl)-3-((tert-butoxycarbonyl)amino)butanoic acid (C21H25NO4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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.

(R)-4-([1,1'-Biphenyl]-4-yl)-3-((tert-butoxycarbonyl)amino)butanoic acid (CAS 2411591-20-1), molecular formula C21H25NO4 and molecular weight 355.43 g/mol, is a CATO reference standard with documented purity and traceability.

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.
