Chemical Structure
Description
As a certified reference material (CRM), Methyl 5-DoXYL-stearate, free radical 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.
Methyl 5-DoXYL-stearate, free radical (CAS 38568-24-0) is a high-purity analytical reference standard with the molecular formula C23H44NO4 and a molecular weight of 398.60 g/mol.
Methyl 5-DoXYL-stearate, free radical (C23H44NO4) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
