Chemical Structure
Description
The occurrence of 5-(3-Methylphenyl)-1-pentene is closely related to an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-(3-Methylphenyl)-1-pentene (CAS 51125-15-6) is a high-purity analytical reference standard with the molecular formula C12H16 and a molecular weight of 160.26 g/mol.
5-(3-Methylphenyl)-1-pentene (C12H16) contains an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), 5-(3-Methylphenyl)-1-pentene 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.
