Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(6-FLUORO-1H-INDOL-3-YL)-3,6-DIHYDRO-2H-PYRIDINE-1-CARBOXYLIC ACID TERT-BUTYL ESTER.

4-(6-FLUORO-1H-INDOL-3-YL)-3,6-DIHYDRO-2H-PYRIDINE-1-CARBOXYLIC ACID TERT-BUTYL ESTER (CAS 935679-13-3) is a high-purity analytical reference standard with the molecular formula C18H21FN2O2 and a molecular weight of 316.37 g/mol.

4-(6-FLUORO-1H-INDOL-3-YL)-3,6-DIHYDRO-2H-PYRIDINE-1-CARBOXYLIC ACID TERT-BUTYL ESTER (C18H21FN2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.

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.
