Chemical Structure
Description
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.
Methyl 2-(3,4-dichlorophenyl)-2-(4-nitrophenyl)acetate (CAS 1923065-87-5), molecular formula C15H11Cl2NO4 and molecular weight 340.16 g/mol, is a CATO reference standard with documented purity and traceability.
Methyl 2-(3,4-dichlorophenyl)-2-(4-nitrophenyl)acetate (C15H11Cl2NO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
