Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 283.75 g/mol gives 4-[(4-Chloro-1-naphthyl)oxy]-2-methylphenylamine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-[(4-Chloro-1-naphthyl)oxy]-2-methylphenylamine (CAS 946743-13-1), a certified reference material (molecular formula C17H14ClNO, MW 283.75 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 4-[(4-Chloro-1-naphthyl)oxy]-2-methylphenylamine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 283.75 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
