2-Hydroxy-5-octadecylbenzoic acid CAS 25707-99-7

Description

Compared with other compounds in its class, the molecular weight of 390.60 g/mol gives 2-Hydroxy-5-octadecylbenzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Hydroxy-5-octadecylbenzoic acid (CAS 25707-99-7) is a high-purity analytical reference standard with the molecular formula C25H42O3 and a molecular weight of 390.60 g/mol.

2-Hydroxy-5-octadecylbenzoic acid (C25H42O3) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

CATO manufactures 2-Hydroxy-5-octadecylbenzoic acid 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.
