4,4'-(Pyridine-2,6-diyl)dibenzaldehyde CAS 509078-07-3

Description

Compared with other compounds in its class, the molecular weight of 287.31 g/mol gives 4,4'-(Pyridine-2,6-diyl)dibenzaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4,4'-(Pyridine-2,6-diyl)dibenzaldehyde (CAS 509078-07-3), molecular formula C19H13NO2 and molecular weight 287.31 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 4,4'-(Pyridine-2,6-diyl)dibenzaldehyde is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 287.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
