Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-METHOXY-2-CYCLOPENTEN-1-ONE 3-methoxycyclopent-2-enone 4683-50-5.
3-METHOXY-2-CYCLOPENTEN-1-ONE 3-methoxycyclopent-2-enone 4683-50-5 (CAS 4683-50-5), molecular formula C6H8O2 and molecular weight 112.13 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 3-METHOXY-2-CYCLOPENTEN-1-ONE 3-methoxycyclopent-2-enone 4683-50-5 is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 112.13 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.
As a certified reference material (CRM), 3-METHOXY-2-CYCLOPENTEN-1-ONE 3-methoxycyclopent-2-enone 4683-50-5 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.
