Chemical Structure

(2E,4E)-N,N-Diphenylhexa-2,4-dienamide CAS 61859-44-7 chemical structure

Description

(2E,4E)-N,N-Diphenylhexa-2,4-dienamide (CAS 61859-44-7), molecular formula C18H17NO and molecular weight 263.33 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (2E,4E)-N,N-Diphenylhexa-2,4-dienamide (C18H17NO) 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

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.
