Ethyl 1-formylcyclopentanecarboxylate (CAS 21744-91-2) is a high-purity analytical reference standard with the molecular formula C9H14O3 and a molecular weight of 170.21 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Ethyl 1-formylcyclopentanecarboxylate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 170.21 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.
