Description
CATO supplies ethyl 3-{4-[(2-chloroacetyl)oxy]-2-fluoroanilino}-2-cyanoacrylate (CAS 239081-33-5), a certified reference material (molecular formula C14H12ClFN2O4, MW 326.71 g/mol) for analytical method development and quality control.
The molecular framework of ethyl 3-{4-[(2-chloroacetyl)oxy]-2-fluoroanilino}-2-cyanoacrylate (C14H12ClFN2O4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures ethyl 3-{4-[(2-chloroacetyl)oxy]-2-fluoroanilino}-2-cyanoacrylate 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.
