Chemical Structure

C26 Diaromatic sterane CAS 103908-63-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 348.56 g/mol gives C26 Diaromatic sterane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

C26 Diaromatic sterane (CAS 103908-63-0), molecular formula C26H36 and molecular weight 348.56 g/mol, is a CATO reference standard with documented purity and traceability.

C26 Diaromatic sterane (C26H36) contains a polycyclic aromatic 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.

CATO manufactures C26 Diaromatic sterane under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
