Chemical Structure

3-Nitro-4-(pyrimidin-2-ylsulfanyl)benzaldehyde CAS 663206-26-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 261.26 g/mol gives 3-Nitro-4-(pyrimidin-2-ylsulfanyl)benzaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-Nitro-4-(pyrimidin-2-ylsulfanyl)benzaldehyde (CAS 663206-26-6), molecular formula C11H7N3O3S and molecular weight 261.26 g/mol, is a CATO reference standard with documented purity and traceability.

3-Nitro-4-(pyrimidin-2-ylsulfanyl)benzaldehyde (C11H7N3O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
