Chemical Structure

Nonadecylbenzene CAS 29136-19-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 344.62 g/mol gives Nonadecylbenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Nonadecylbenzene (CAS 29136-19-4), molecular formula C25H44 and molecular weight 344.62 g/mol, is a CATO reference standard with documented purity and traceability.

Nonadecylbenzene (C25H44) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 Nonadecylbenzene 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.
