Chemical Structure

Methyl 7-(5-oxocyclopent-1-en-1-yl)heptanoate CAS 34546-57-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl 7-(5-oxocyclopent-1-en-1-yl)heptanoate.

Methyl 7-(5-oxocyclopent-1-en-1-yl)heptanoate (CAS 34546-57-1), molecular formula C13H20O3 and molecular weight 224.30 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Methyl 7-(5-oxocyclopent-1-en-1-yl)heptanoate 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.

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

As a certified reference material (CRM), Methyl 7-(5-oxocyclopent-1-en-1-yl)heptanoate 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.
