Chemical Structure
Description
Structurally, 3-Chloro-n-[(4-ethoxyphenyl)methyl]-4-methoxyaniline (C16H18ClNO2) contains a nitrogen-containing heterocyclic scaffold, 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 291.77 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
3-Chloro-n-[(4-ethoxyphenyl)methyl]-4-methoxyaniline (CAS 851619-65-3), molecular formula C16H18ClNO2 and molecular weight 291.77 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
