Chemical Structure

3-Chlorofluoranthene CAS 25911-51-7 chemical structure

Description

Owing to chlorine substitution, a polycyclic aromatic system, 3-Chlorofluoranthene is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 236.70 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

3-Chlorofluoranthene (CAS 25911-51-7) is a high-purity analytical reference standard with the molecular formula C16H9Cl and a molecular weight of 236.70 g/mol.

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), 3-Chlorofluoranthene 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.
