4-(3-Bromophenyl)-2-chloro-7,8-dihydro-5H-pyrano[4,3-b]pyridine-3-carbonitrile CAS 1707581-83-6

Description

The molecular framework of 4-(3-Bromophenyl)-2-chloro-7,8-dihydro-5H-pyrano[4,3-b]pyridine-3-carbonitrile (C15H10BrClN2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

4-(3-Bromophenyl)-2-chloro-7,8-dihydro-5H-pyrano[4,3-b]pyridine-3-carbonitrile (CAS 1707581-83-6), molecular formula C15H10BrClN2O and molecular weight 349.61 g/mol, is a CATO reference standard with documented purity and traceability.

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.
