Chemical Structure
Description
(3S)-6-fluoro-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid (C10H16FNO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. 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.
(3S)-6-fluoro-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid (CAS 1161833-81-3) is a high-purity analytical reference standard with the molecular formula C10H16FNO2 and a molecular weight of 201.24 g/mol.
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.
