Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 360.65 g/mol gives Chlorpyrifos (diethyl-D10) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Chlorpyrifos (diethyl-D10) (CAS 285138-81-0), molecular formula C9HD10Cl3NO3PS and molecular weight 360.65 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Chlorpyrifos (diethyl-D10) (C9HD10Cl3NO3PS) contains deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a phosphonate group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.5, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 360.65 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
