Chemical Structure
Description
The molecular framework of N-(tert-Butoxycarbonyl)-DL-phenylalaninol (C14H21NO3) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
N-(tert-Butoxycarbonyl)-DL-phenylalaninol (CAS 145149-48-0) is a high-purity analytical reference standard with the molecular formula C14H21NO3 and a molecular weight of 251.32 g/mol.
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), N-(tert-Butoxycarbonyl)-DL-phenylalaninol 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.
