R-(-)-Phencyphos hydrate CAS 953776-24-4

Description

The occurrence of R-(-)-Phencyphos hydrate is closely related to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

R-(-)-Phencyphos hydrate (CAS 953776-24-4), molecular formula C11H15O4PH2O and molecular weight 260.23 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C11H15O4PH2O, R-(-)-Phencyphos hydrate contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 260.23 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).

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), R-(-)-Phencyphos hydrate 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.
