Chemical Structure
Description
As a certified reference material (CRM), Bis(1-naphthyl)chlorophosphine 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.
Bis(1-naphthyl)chlorophosphine (CAS 36042-99-6), molecular formula C20H14ClP and molecular weight 320.75 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to organophosphorus functionality, chlorine substitution, a polycyclic aromatic system, Bis(1-naphthyl)chlorophosphine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 320.75 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
