Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 389.08 g/mol gives Fipronil Desulfinyl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Fipronil Desulfinyl (CAS 205650-65-3), a certified reference material (molecular formula C12H4Cl2F6N4, MW 389.08 g/mol) for analytical method development and quality control.
The molecular framework of Fipronil Desulfinyl (C12H4Cl2F6N4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Fipronil Desulfinyl 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.
