Chemical Structure
Description
As a certified reference material (CRM), 5-Chloro-2-(1h-pyrrol-1-yl)aniline 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.
5-Chloro-2-(1h-pyrrol-1-yl)aniline (CAS 15814-76-3), molecular formula C10H9ClN2 and molecular weight 192.64 g/mol, is a CATO reference standard with documented purity and traceability.
5-Chloro-2-(1h-pyrrol-1-yl)aniline (C10H9ClN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
