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.
(S)-N-(pyrrolidin-3-yl)-2,3-dihydrobenzo[b][1,4]dioxine-5-carboxamide hydrochloride (CAS 1353995-55-7), molecular formula C13H16N2O3HCl and molecular weight 284.74 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C13H16N2O3HCl, (S)-N-(pyrrolidin-3-yl)-2,3-dihydrobenzo[b][1,4]dioxine-5-carboxamide hydrochloride contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 284.74 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.
