Chemical Structure

<I>N</I>-Cyclohexylmaleimide CAS 1631-25-0 chemical structure

Description

CATO supplies <I>N</I>-Cyclohexylmaleimide (CAS 1631-25-0), a certified reference material (molecular formula C10H13NO2, MW 179.22 g/mol) for analytical method development and quality control.

The molecular framework of <I>N</I>-Cyclohexylmaleimide (C10H13NO2) is characterized by an amino-acid-derived structure, 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 <I>N</I>-Cyclohexylmaleimide 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.
