Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 36332-93-1 7STP871R4S Methylarachidic acid UNII-7STP871R4S 18-Methyleicosanoic acid Anteisoheneicosanoic acid Eicosanoic acid, 18-methyl- 18-MEA.
36332-93-1 7STP871R4S Methylarachidic acid UNII-7STP871R4S 18-Methyleicosanoic acid Anteisoheneicosanoic acid Eicosanoic acid, 18-methyl- 18-MEA (CAS 36332-93-1) is a high-purity analytical reference standard with the molecular formula C21H39D3O2 and a molecular weight of 329.58 g/mol.
Based on its molecular formula C21H39D3O2, 36332-93-1 7STP871R4S Methylarachidic acid UNII-7STP871R4S 18-Methyleicosanoic acid Anteisoheneicosanoic acid Eicosanoic acid, 18-methyl- 18-MEA contains deuterium isotope labeling, 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 329.58 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.
As a certified reference material (CRM), 36332-93-1 7STP871R4S Methylarachidic acid UNII-7STP871R4S 18-Methyleicosanoic acid Anteisoheneicosanoic acid Eicosanoic acid, 18-methyl- 18-MEA 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.
