Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 275.20 g/mol gives Paraoxon distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Paraoxon (CAS 311-45-5) is a high-purity analytical reference standard with the molecular formula C10H14NO6P and a molecular weight of 275.20 g/mol.
Based on its molecular formula C10H14NO6P, Paraoxon contains a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 275.20 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.
As a certified reference material (CRM), Paraoxon 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.
