Chemical Structure

3,3,5,5-Tetramethyloxan-4-one CAS 89050-76-0 chemical structure

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.

CATO supplies 3,3,5,5-Tetramethyloxan-4-one (CAS 89050-76-0), a certified reference material (molecular formula C9H16O2, MW 156.22 g/mol) for analytical method development and quality control.

The molecular framework of 3,3,5,5-Tetramethyloxan-4-one (C9H16O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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