Description

Compared with other compounds in its class, the molecular weight of 257.69 g/mol gives 4-Cyano-3-ethyl-5-formylbenzene-1-sulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Cyano-3-ethyl-5-formylbenzene-1-sulfonyl chloride (CAS 1807283-08-4), molecular formula C10H8ClNO3S and molecular weight 257.69 g/mol, is a CATO reference standard with documented purity and traceability.

4-Cyano-3-ethyl-5-formylbenzene-1-sulfonyl chloride (C10H8ClNO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

As a certified reference material (CRM), 4-Cyano-3-ethyl-5-formylbenzene-1-sulfonyl chloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
