Chemical Structure

Heptadecylbenzene CAS 14752-75-1 chemical structure

Description

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

Heptadecylbenzene (CAS 14752-75-1), molecular formula C23H40 and molecular weight 316.56 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Heptadecylbenzene (C23H40) is characterized by an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), Heptadecylbenzene 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.
