Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Methyl 2-(3-oxo-2-pentylcyclopent-1-en-1-yl)acetate (CAS 24863-70-5) is a high-purity analytical reference standard with the molecular formula C13H20O3 and a molecular weight of 224.30 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Methyl 2-(3-oxo-2-pentylcyclopent-1-en-1-yl)acetate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 224.30 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.
As a certified reference material (CRM), Methyl 2-(3-oxo-2-pentylcyclopent-1-en-1-yl)acetate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
