9-Chlorophenanthrene CAS 947-72-8 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.

9-Chlorophenanthrene (CAS 947-72-8) is a high-purity analytical reference standard with the molecular formula C14H9Cl and a molecular weight of 212.67 g/mol.

Owing to chlorine substitution, a polycyclic aromatic system, 9-Chlorophenanthrene is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 212.67 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

As a certified reference material (CRM), 9-Chlorophenanthrene 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.
