Compared with other compounds in its class, the molecular weight of 312.34 g/mol gives {[(1-Propionyl-2,3-dihydro-1H-indol-5-yl)-sulfonyl]amino}acetic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies {[(1-Propionyl-2,3-dihydro-1H-indol-5-yl)-sulfonyl]amino}acetic acid (CAS 899718-42-4), a certified reference material (molecular formula C13H16N2O5S, MW 312.34 g/mol) for analytical method development and quality control.
The molecular framework of {[(1-Propionyl-2,3-dihydro-1H-indol-5-yl)-sulfonyl]amino}acetic acid (C13H16N2O5S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
