Chemical Structure
Description
The occurrence of 5-DOXYL Stearic acid, ammonium salt is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-DOXYL Stearic acid, ammonium salt (CAS 2315262-05-4), molecular formula C22H41NO4H4N and molecular weight 401.61 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C22H41NO4H4N, 5-DOXYL Stearic acid, ammonium salt contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 401.61 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
As a certified reference material (CRM), 5-DOXYL Stearic acid, ammonium salt 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.
