Chemical Structure
Description
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 supplies (S)-3-(tert-Butoxycarbonylamino)-3-(4-hydroxyphenyl)propanoic acid (CAS 499995-80-1), a certified reference material (molecular formula C14H19NO5, MW 281.30 g/mol) for analytical method development and quality control.
The molecular framework of (S)-3-(tert-Butoxycarbonylamino)-3-(4-hydroxyphenyl)propanoic acid (C14H19NO5) 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 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.
As a certified reference material (CRM), (S)-3-(tert-Butoxycarbonylamino)-3-(4-hydroxyphenyl)propanoic acid 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.
