n-Isobutyl-2,4-dimethoxyaniline CAS 1019526-11-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including n-Isobutyl-2,4-dimethoxyaniline.

n-Isobutyl-2,4-dimethoxyaniline (CAS 1019526-11-4) is a high-purity analytical reference standard with the molecular formula C12H19NO2 and a molecular weight of 209.28 g/mol.

n-Isobutyl-2,4-dimethoxyaniline (C12H19NO2) contains an amino-acid-derived structure, an amide 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
