Chemical Structure

4-n-Pentyldibenzothiophene CAS 147792-34-5 chemical structure

Description

As a certified reference material (CRM), 4-n-Pentyldibenzothiophene 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.

4-n-Pentyldibenzothiophene (CAS 147792-34-5), molecular formula C17H18S and molecular weight 254.39 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4-n-Pentyldibenzothiophene (C17H18S) contains sulfur-containing functionality, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 254.39 g/mol, it falls into the medium-molecular-weight range. 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.
