Description
As a certified reference material (CRM), Methyl (2S)-2-amino-3-(2-oxoindolin-3-yl)propanoate hydrochloride 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.
CATO supplies Methyl (2S)-2-amino-3-(2-oxoindolin-3-yl)propanoate hydrochloride (CAS 289635-85-4), a certified reference material (molecular formula C12H14N2O3HCl, MW 270.71 g/mol) for analytical method development and quality control.
Methyl (2S)-2-amino-3-(2-oxoindolin-3-yl)propanoate hydrochloride (C12H14N2O3HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
