Description

The occurrence of 35675-80-0 I5T6470120 Methyltricaprylylammonium bromide UNII-I5T6470120 1-Octanaminium, N-methyl-N,N-dioctyl-, bromide (1:1) 1-Octanaminium, N-methyl-N,N-dioctyl-, bromide Aliquat 138 Methyltrioctylammonium bromide Trioctylmethylammonium bromide is closely related to bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

35675-80-0 I5T6470120 Methyltricaprylylammonium bromide UNII-I5T6470120 1-Octanaminium, N-methyl-N,N-dioctyl-, bromide (1:1) 1-Octanaminium, N-methyl-N,N-dioctyl-, bromide Aliquat 138 Methyltrioctylammonium bromide Trioctylmethylammonium bromide (CAS 35675-80-0), molecular formula C25H54NBr and molecular weight 448.62 g/mol, is a CATO reference standard with documented purity and traceability.

35675-80-0 I5T6470120 Methyltricaprylylammonium bromide UNII-I5T6470120 1-Octanaminium, N-methyl-N,N-dioctyl-, bromide (1:1) 1-Octanaminium, N-methyl-N,N-dioctyl-, bromide Aliquat 138 Methyltrioctylammonium bromide Trioctylmethylammonium bromide (C25H54NBr) contains bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.

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.
