Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Acetyl-2H-cyclohepta[b]furan-2-one.
CATO supplies 3-Acetyl-2H-cyclohepta[b]furan-2-one (CAS 22460-76-0), a certified reference material (molecular formula C11H8O3, MW 188.18 g/mol) for analytical method development and quality control.
Based on its molecular formula C11H8O3, 3-Acetyl-2H-cyclohepta[b]furan-2-one contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 188.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
