Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (S)-2-amino-3-(5-hydroxy-1H-indol-3-yl)propanoic acid dihydrate (CAS 145224-90-4), a certified reference material (molecular formula C11H12N2O3H2O, MW 238.24 g/mol) for analytical method development and quality control.
The molecular framework of (S)-2-amino-3-(5-hydroxy-1H-indol-3-yl)propanoic acid dihydrate (C11H12N2O3H2O) is characterized by an amino-acid-derived structure, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), (S)-2-amino-3-(5-hydroxy-1H-indol-3-yl)propanoic acid dihydrate 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.
