Chemical Structure
Description
As a certified reference material (CRM), 4-(Hexadecyloxy)benzoic acid 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.
CATO supplies 4-(Hexadecyloxy)benzoic acid (CAS 15872-48-7), a certified reference material (molecular formula C23H38O3, MW 362.55 g/mol) for analytical method development and quality control.
Based on its molecular formula C23H38O3, 4-(Hexadecyloxy)benzoic acid contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 362.55 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
