Chemical Structure

3,5-Dimethylheptan-4-one CAS 19549-84-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 142.24 g/mol gives 3,5-Dimethylheptan-4-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3,5-Dimethylheptan-4-one (CAS 19549-84-9), molecular formula C9H18O and molecular weight 142.24 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3,5-Dimethylheptan-4-one (C9H18O) is characterized by 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.

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.
