3-Ethoxy-5-methylpyridine CAS 1256825-14-5

Description

Compared with other compounds in its class, the molecular weight of 137.18 g/mol gives 3-Ethoxy-5-methylpyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-Ethoxy-5-methylpyridine (CAS 1256825-14-5), molecular formula C8H11NO and molecular weight 137.18 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 3-Ethoxy-5-methylpyridine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 137.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
