Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4,4'-(Hexane-3,4-diyl)dicyclohexanone.
CATO supplies 4,4'-(Hexane-3,4-diyl)dicyclohexanone (CAS 33665-35-9), a certified reference material (molecular formula C18H30O2, MW 278.43 g/mol) for analytical method development and quality control.
The molecular framework of 4,4'-(Hexane-3,4-diyl)dicyclohexanone (C18H30O2) is characterized by a steroid core, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
