Chemical Structure

1,5-Dioxepan-2-one CAS 35438-57-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 116.12 g/mol gives 1,5-Dioxepan-2-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1,5-Dioxepan-2-one (CAS 35438-57-4), molecular formula C5H8O3 and molecular weight 116.12 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1,5-Dioxepan-2-one (C5H8O3) 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.

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.
