4-(2,3-Dihydrothieno[3,4-b][1,4]dioxin-5-yl)quinoline-6-carbaldehyde CAS 1119899-28-3

Description

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.

4-(2,3-Dihydrothieno[3,4-b][1,4]dioxin-5-yl)quinoline-6-carbaldehyde (CAS 1119899-28-3), molecular formula C16H11NO3S and molecular weight 297.33 g/mol, is a CATO reference standard with documented purity and traceability.

4-(2,3-Dihydrothieno[3,4-b][1,4]dioxin-5-yl)quinoline-6-carbaldehyde (C16H11NO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
