Chemical Structure
Description
The occurrence of Ethyl 4-((4-heptylbenzylidene)amino)benzoate is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ethyl 4-((4-heptylbenzylidene)amino)benzoate (CAS 477856-77-2) is a high-purity analytical reference standard with the molecular formula C23H29NO2 and a molecular weight of 351.48 g/mol.
The molecular framework of Ethyl 4-((4-heptylbenzylidene)amino)benzoate (C23H29NO2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
CATO manufactures Ethyl 4-((4-heptylbenzylidene)amino)benzoate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
