Chemical Structure

Pentadecylbenzene CAS 2131-18-2 chemical structure

Description

The occurrence of Pentadecylbenzene is closely related to an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Pentadecylbenzene (CAS 2131-18-2) is a high-purity analytical reference standard with the molecular formula C21H36 and a molecular weight of 288.51 g/mol.

Based on its molecular formula C21H36, Pentadecylbenzene contains an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 288.51 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), Pentadecylbenzene 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.
