Chemical Structure
Description
As a certified reference material (CRM), tert-Butyl (S)-2-amino-3-(3-bromo-2-methylphenyl)propanoate 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.
tert-Butyl (S)-2-amino-3-(3-bromo-2-methylphenyl)propanoate (CAS 2142633-49-4) is a high-purity analytical reference standard with the molecular formula C14H20BrNO2 and a molecular weight of 314.22 g/mol.
The molecular framework of tert-Butyl (S)-2-amino-3-(3-bromo-2-methylphenyl)propanoate (C14H20BrNO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
