Compared with other compounds in its class, the molecular weight of 360.80 g/mol gives Pyraclofos distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Pyraclofos (CAS 77458-01-6), molecular formula C14H18ClN2O3PS and molecular weight 360.80 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C14H18ClN2O3PS, Pyraclofos contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a phosphonate group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 360.80 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), Pyraclofos 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.
