Chemical Structure
Description
The occurrence of Methyl 4-(1-((tert-butoxycarbonyl)amino)-2-hydroxyethyl)benzoate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Methyl 4-(1-((tert-butoxycarbonyl)amino)-2-hydroxyethyl)benzoate (CAS 156143-81-6), molecular formula C15H21NO5 and molecular weight 295.33 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Methyl 4-(1-((tert-butoxycarbonyl)amino)-2-hydroxyethyl)benzoate (C15H21NO5) 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.
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.
