Chemical Structure

Methyl (2Z)-2-{1-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-1H-indol-3-yl}-3-[(4-methoxyphenyl)amino]prop-2-enoate CAS 303152-90-1 chemical structure

Description

The occurrence of Methyl (2Z)-2-{1-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-1H-indol-3-yl}-3-[(4-methoxyphenyl)amino]prop-2-enoate is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Methyl (2Z)-2-{1-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-1H-indol-3-yl}-3-[(4-methoxyphenyl)amino]prop-2-enoate (CAS 303152-90-1), molecular formula C25H19ClF3N3O3 and molecular weight 501.88 g/mol, is a CATO reference standard with documented purity and traceability.

Methyl (2Z)-2-{1-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-1H-indol-3-yl}-3-[(4-methoxyphenyl)amino]prop-2-enoate (C25H19ClF3N3O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, 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. 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.
