Chemical Structure
Description
2-(Oxetan-3-ylidene)acetonitrile (C5H5NO) contains an amide group, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
2-(Oxetan-3-ylidene)acetonitrile (CAS 1123787-67-6) is a high-purity analytical reference standard with the molecular formula C5H5NO and a molecular weight of 95.10 g/mol.
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), 2-(Oxetan-3-ylidene)acetonitrile 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.
