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.
CATO supplies 3-Chloro-N-[2-(2-ethoxyethoxy)benzyl]-4-methoxyaniline (CAS 1040685-88-8), a certified reference material (molecular formula C18H22ClNO3, MW 335.83 g/mol) for analytical method development and quality control.
Based on its molecular formula C18H22ClNO3, 3-Chloro-N-[2-(2-ethoxyethoxy)benzyl]-4-methoxyaniline contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 335.83 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
