Chemical Structure
Description
N-(4-Amino-2-methylphenyl)-2-[2-(sec-butyl)-phenoxy]butanamide (C21H28N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
N-(4-Amino-2-methylphenyl)-2-[2-(sec-butyl)-phenoxy]butanamide (CAS 1020055-25-7) is a high-purity analytical reference standard with the molecular formula C21H28N2O2 and a molecular weight of 340.46 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
