Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 394.34 g/mol gives Trifloxystrobin (free acid) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Trifloxystrobin (free acid) (CAS 252913-85-2), a certified reference material (molecular formula C19H17F3N2O4, MW 394.34 g/mol) for analytical method development and quality control.
The molecular framework of Trifloxystrobin (free acid) (C19H17F3N2O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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.
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), Trifloxystrobin (free acid) 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.
