3-Methyl-2-{[(2-methyl-1-propionyl-2,3-dihydro-1H-indol-5-yl)sulfonyl]amino}butanoic acid CAS 1396965-02-8 chemical structure

Description

As a certified reference material (CRM), 3-Methyl-2-{[(2-methyl-1-propionyl-2,3-dihydro-1H-indol-5-yl)sulfonyl]amino}butanoic acid 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.

3-Methyl-2-{[(2-methyl-1-propionyl-2,3-dihydro-1H-indol-5-yl)sulfonyl]amino}butanoic acid (CAS 1396965-02-8) is a high-purity analytical reference standard with the molecular formula C17H24N2O5S and a molecular weight of 368.45 g/mol.

The molecular framework of 3-Methyl-2-{[(2-methyl-1-propionyl-2,3-dihydro-1H-indol-5-yl)sulfonyl]amino}butanoic acid (C17H24N2O5S) is characterized by a flavonoid core, 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).

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.
