Chemical Structure
Description
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 supplies (E)-4-Ethoxy-2-(trifluoromethyl)-2-((trimethylsilyl)oxy)but-3-enenitrile (CAS 244074-91-7), a certified reference material (molecular formula C10H16F3NO2Si, MW 267.32 g/mol) for analytical method development and quality control.
(E)-4-Ethoxy-2-(trifluoromethyl)-2-((trimethylsilyl)oxy)but-3-enenitrile (C10H16F3NO2Si) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.
As a certified reference material (CRM), (E)-4-Ethoxy-2-(trifluoromethyl)-2-((trimethylsilyl)oxy)but-3-enenitrile 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.
