Chemical Structure
Description
(E)-4-(3-(benzo[d][1,3]dioxol-5-yl)acryloyl)phenyl 2-chlorobenzoate (C23H15ClO5) contains a flavonoid core, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
(E)-4-(3-(benzo[d][1,3]dioxol-5-yl)acryloyl)phenyl 2-chlorobenzoate (CAS 306730-67-6), molecular formula C23H15ClO5 and molecular weight 406.82 g/mol, is a CATO reference standard with documented purity and traceability.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
