Chemical Structure
Description
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.
3-(1-Ethyl-1,2,3,6-tetrahydropyridin-4-yl)-5-nitro-1H-indole (CAS 1152720-77-8), molecular formula C15H17N3O2 and molecular weight 271.31 g/mol, is a CATO reference standard with documented purity and traceability.
3-(1-Ethyl-1,2,3,6-tetrahydropyridin-4-yl)-5-nitro-1H-indole (C15H17N3O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
