Chemical Structure
Description
3-(2-Methylenecyclopropyl)-2-oxopropanoic acid (CAS 5746-24-7) is a high-purity analytical reference standard with the molecular formula C7H8O3 and a molecular weight of 140.14 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 3-(2-Methylenecyclopropyl)-2-oxopropanoic acid is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 140.14 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.
