(E)-4-(Octadecyloxy)-4-oxobut-2-enoic acid CAS 1741-93-1

Description

Compared with other compounds in its class, the molecular weight of 368.55 g/mol gives (E)-4-(Octadecyloxy)-4-oxobut-2-enoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(E)-4-(Octadecyloxy)-4-oxobut-2-enoic acid (CAS 1741-93-1) is a high-purity analytical reference standard with the molecular formula C22H40O4 and a molecular weight of 368.55 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, (E)-4-(Octadecyloxy)-4-oxobut-2-enoic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 368.55 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.
