6-(4-Ethylpiperazin-1-yl)-4-methylnicotinaldehyde CAS 1355195-82-2

Description

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.

6-(4-Ethylpiperazin-1-yl)-4-methylnicotinaldehyde (CAS 1355195-82-2), molecular formula C13H19N3O and molecular weight 233.31 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 6-(4-Ethylpiperazin-1-yl)-4-methylnicotinaldehyde (C13H19N3O) is characterized by a nitrogen-containing heterocyclic scaffold, 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.
