Chemical Structure

(E)-4-(4-chlorophenyl)-4-oxobut-2-enoic acid 3-(4-Chlorobenzoyl)acrylic acid 6269-33-6 CAS 6269-33-6 chemical structure

Description

The occurrence of (E)-4-(4-chlorophenyl)-4-oxobut-2-enoic acid 3-(4-Chlorobenzoyl)acrylic acid 6269-33-6 is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (E)-4-(4-chlorophenyl)-4-oxobut-2-enoic acid 3-(4-Chlorobenzoyl)acrylic acid 6269-33-6 (CAS 6269-33-6), a certified reference material (molecular formula C10H7ClO3, MW 210.61 g/mol) for analytical method development and quality control.

(E)-4-(4-chlorophenyl)-4-oxobut-2-enoic acid 3-(4-Chlorobenzoyl)acrylic acid 6269-33-6 (C10H7ClO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
