Chemical Structure
Description
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.
CATO supplies 5-(2,3-Dihydrobenzo[b][1,4]dioxin-5-yl)furan-2-carbaldehyde (CAS 1706447-89-3), a certified reference material (molecular formula C13H10O4, MW 230.22 g/mol) for analytical method development and quality control.
5-(2,3-Dihydrobenzo[b][1,4]dioxin-5-yl)furan-2-carbaldehyde (C13H10O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
