Chemical Structure

2-Propionylpyridine CAS 3238-55-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 135.16 g/mol gives 2-Propionylpyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Propionylpyridine (CAS 3238-55-9) is a high-purity analytical reference standard with the molecular formula C8H9NO and a molecular weight of 135.16 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 2-Propionylpyridine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 135.16 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
