Chemical Structure
Description
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.
5-chloro-4-iodo-1-(4-methylbenzenesulfonyl)-1H-pyrrolo[2,3-b]pyridine (CAS 1350375-64-2), molecular formula C14H24ClIN2O2S and molecular weight 446.78 g/mol, is a CATO reference standard with documented purity and traceability.
5-chloro-4-iodo-1-(4-methylbenzenesulfonyl)-1H-pyrrolo[2,3-b]pyridine (C14H24ClIN2O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/iodine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), 5-chloro-4-iodo-1-(4-methylbenzenesulfonyl)-1H-pyrrolo[2,3-b]pyridine 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.
