Methyl 2-(3-cyano-4-nitrophenyl)-2-(3,4-dimethoxyphenyl)acetate CAS 1923065-68-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl 2-(3-cyano-4-nitrophenyl)-2-(3,4-dimethoxyphenyl)acetate.

Methyl 2-(3-cyano-4-nitrophenyl)-2-(3,4-dimethoxyphenyl)acetate (CAS 1923065-68-2), molecular formula C18H16N2O6 and molecular weight 356.33 g/mol, is a CATO reference standard with documented purity and traceability.

Methyl 2-(3-cyano-4-nitrophenyl)-2-(3,4-dimethoxyphenyl)acetate (C18H16N2O6) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
