Chemical Structure
Description
Bis(2-(3-(2-chloro-6-fluorophenyl)-5-methylisoxazol-4-yl)-4-(2-methoxyphenyl)piperazin-1-yl)methanone (CAS 497060-57-8), molecular formula C43H40Cl2F2N6O5 and molecular weight 829.72 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Bis(2-(3-(2-chloro-6-fluorophenyl)-5-methylisoxazol-4-yl)-4-(2-methoxyphenyl)piperazin-1-yl)methanone (C43H40Cl2F2N6O5) 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
