Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Ethoxy-N-(propan-2-yl)aniline.
4-Ethoxy-N-(propan-2-yl)aniline (CAS 16495-69-5) is a high-purity analytical reference standard with the molecular formula C11H17NO and a molecular weight of 179.26 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 4-Ethoxy-N-(propan-2-yl)aniline is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 179.26 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.
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.
