Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 327.58 g/mol gives Fenchlorphos-d distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Fenchlorphos-d (CAS 33576-72-6) is a high-purity analytical reference standard with the molecular formula C8H2D6Cl3O3PS and a molecular weight of 327.58 g/mol.
Structurally, Fenchlorphos-d (C8H2D6Cl3O3PS) contains deuterium isotope labeling, a sulfone group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.5, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 327.58 g/mol, it falls into the moderately-high-molecular-weight range. 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), Fenchlorphos-d 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.
