Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-3-(5-bromo-1H-indol-3-yl)-2-((tert-butoxycarbonyl)amino)propanoic acid.
CATO supplies (S)-3-(5-bromo-1H-indol-3-yl)-2-((tert-butoxycarbonyl)amino)propanoic acid (CAS 75816-20-5), a certified reference material (molecular formula C16H19BrN2O4, MW 383.24 g/mol) for analytical method development and quality control.
The molecular framework of (S)-3-(5-bromo-1H-indol-3-yl)-2-((tert-butoxycarbonyl)amino)propanoic acid (C16H19BrN2O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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. 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.
