Chemical Structure

di-tert-Butyl 3-oxopentanedioate CAS 28009-80-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 258.31 g/mol gives di-tert-Butyl 3-oxopentanedioate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

di-tert-Butyl 3-oxopentanedioate (CAS 28009-80-5) is a high-purity analytical reference standard with the molecular formula C13H22O5 and a molecular weight of 258.31 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, di-tert-Butyl 3-oxopentanedioate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 258.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
