Chemical Structure
Description
(S)-2-((tert-Butoxycarbonyl)amino)-3-(1H-pyrrolo[2,3-b]pyridin-3-yl)propanoic acid (CAS 146610-21-1), molecular formula C15H19N3O4 and molecular weight 305.33 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, (S)-2-((tert-Butoxycarbonyl)amino)-3-(1H-pyrrolo[2,3-b]pyridin-3-yl)propanoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 305.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), (S)-2-((tert-Butoxycarbonyl)amino)-3-(1H-pyrrolo[2,3-b]pyridin-3-yl)propanoic 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.
