Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 321.71 g/mol gives (4-Chlorophenyl)(7-nitro-2,3-dihydrobenzo[b][1,4]dioxin-6-yl)methanol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (4-Chlorophenyl)(7-nitro-2,3-dihydrobenzo[b][1,4]dioxin-6-yl)methanol (CAS 886493-47-6), a certified reference material (molecular formula C15H12ClNO5, MW 321.71 g/mol) for analytical method development and quality control.
(4-Chlorophenyl)(7-nitro-2,3-dihydrobenzo[b][1,4]dioxin-6-yl)methanol (C15H12ClNO5) contains a flavonoid core, an amide group, 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).
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.
