43A41KA91Q 32360-05-7 Stearyl methacrylate Octadecyl methacrylate 2-Propenoic acid, 2-methyl-, octadecyl ester AI3-25418 EINECS 251-013-5 Methacrylic acid, stearyl ester UNII-43A41KA91Q EC 251-013-5 Methacrylic acid, octadecyl ester CAS 32360-05-7 chemical structure

Description

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.

43A41KA91Q 32360-05-7 Stearyl methacrylate Octadecyl methacrylate 2-Propenoic acid, 2-methyl-, octadecyl ester AI3-25418 EINECS 251-013-5 Methacrylic acid, stearyl ester UNII-43A41KA91Q EC 251-013-5 Methacrylic acid, octadecyl ester (CAS 32360-05-7) is a high-purity analytical reference standard with the molecular formula C22H42O2 and a molecular weight of 338.57 g/mol.

43A41KA91Q 32360-05-7 Stearyl methacrylate Octadecyl methacrylate 2-Propenoic acid, 2-methyl-, octadecyl ester AI3-25418 EINECS 251-013-5 Methacrylic acid, stearyl ester UNII-43A41KA91Q EC 251-013-5 Methacrylic acid, octadecyl ester (C22H42O2) contains a carboxylic acid group, 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 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.
