1-(5-Carboxypentyl)-2,3,3-trimethyl-6,7-dihydro-3H-indol-1-ium iodide CAS 865611-47-8

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.

1-(5-Carboxypentyl)-2,3,3-trimethyl-6,7-dihydro-3H-indol-1-ium iodide (CAS 865611-47-8), molecular formula C17H24NO2I and molecular weight 401.28 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C17H24NO2I, 1-(5-Carboxypentyl)-2,3,3-trimethyl-6,7-dihydro-3H-indol-1-ium iodide contains a steroid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 401.28 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
