Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 341.85 g/mol gives (±)-Fenbuconazole-d5 (phenyl-d5) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (±)-Fenbuconazole-d5 (phenyl-d5) (CAS 1398066-06-2), a certified reference material (molecular formula C19H12D5ClN4, MW 341.85 g/mol) for analytical method development and quality control.
(±)-Fenbuconazole-d5 (phenyl-d5) (C19H12D5ClN4) contains deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), (±)-Fenbuconazole-d5 (phenyl-d5) 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.
