Chemical Structure

2,5,5-Trimethylcyclohexan-1-one CAS 33543-18-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 140.22 g/mol gives 2,5,5-Trimethylcyclohexan-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2,5,5-Trimethylcyclohexan-1-one (CAS 33543-18-9), molecular formula C9H16O and molecular weight 140.22 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2,5,5-Trimethylcyclohexan-1-one (C9H16O) contains a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 140.22 g/mol, it falls into the low-molecular-weight range.

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.
