Chemical Structure
Description
The occurrence of Ethyl 4-{[(4-methoxybenzyl)amino]-methyl}benzoate hydrochloride is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ethyl 4-{[(4-methoxybenzyl)amino]-methyl}benzoate hydrochloride (CAS 17841-66-6), molecular formula C18H21NO3HCl and molecular weight 335.83 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Ethyl 4-{[(4-methoxybenzyl)amino]-methyl}benzoate hydrochloride (C18H21NO3HCl) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 335.83 g/mol, it falls into the moderately-high-molecular-weight range. 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.
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.
