Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 494.27 g/mol gives Pyriprole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Pyriprole (CAS 394730-71-3), molecular formula C18H10Cl2F5N5S and molecular weight 494.27 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Pyriprole (C18H10Cl2F5N5S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 494.27 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
CATO manufactures Pyriprole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
