Description
Compared with other compounds in its class, the molecular weight of 242.76 g/mol gives 5-Isobutoxypentane-1-sulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Isobutoxypentane-1-sulfonyl chloride (CAS 1342844-50-1), molecular formula C9H19ClO3S and molecular weight 242.76 g/mol, is a CATO reference standard with documented purity and traceability.
5-Isobutoxypentane-1-sulfonyl chloride (C9H19ClO3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, 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. 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), 5-Isobutoxypentane-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.
