Chemical Structure
Description
CATO supplies 5-Chlorobenzo[b]phosphindole (CAS 33300-85-5), a certified reference material (molecular formula C12H20ClP, MW 230.71 g/mol) for analytical method development and quality control.
5-Chlorobenzo[b]phosphindole (C12H20ClP) contains organophosphorus functionality, 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. 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-Chlorobenzo[b]phosphindole 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.
