Cyclohexanecarboxylic Anhydride CAS 22651-87-2 chemical structure

Description

CATO supplies Cyclohexanecarboxylic Anhydride (CAS 22651-87-2), a certified reference material (molecular formula C14H22O3, MW 238.32 g/mol) for analytical method development and quality control.

The molecular framework of Cyclohexanecarboxylic Anhydride (C14H22O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
