Description
As a certified reference material (CRM), (6)Helicene, racemic mixture of two enantiomers 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.
(6)Helicene, racemic mixture of two enantiomers (CAS 187-83-7) is a high-purity analytical reference standard with the molecular formula C26H16 and a molecular weight of 328.41 g/mol.
Based on its molecular formula C26H16, (6)Helicene, racemic mixture of two enantiomers contains a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 328.41 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
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.
