4-(2-Bromophenyl)-2-chloro-7,8-dihydro-5H-pyrano[4,3-b]pyridine-3-carbonitrile CAS 1707568-95-3

Description

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.

4-(2-Bromophenyl)-2-chloro-7,8-dihydro-5H-pyrano[4,3-b]pyridine-3-carbonitrile (CAS 1707568-95-3) is a high-purity analytical reference standard with the molecular formula C15H10BrClN2O and a molecular weight of 349.61 g/mol.

Based on its molecular formula C15H10BrClN2O, 4-(2-Bromophenyl)-2-chloro-7,8-dihydro-5H-pyrano[4,3-b]pyridine-3-carbonitrile contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 349.61 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.

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.
