Chemical Structure

3-Ethylcyclobutane-1,1-dicarboxylic acid CAS 69647-59-2 chemical structure

Description

The molecular framework of 3-Ethylcyclobutane-1,1-dicarboxylic acid (C8H12O4) 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. 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).

3-Ethylcyclobutane-1,1-dicarboxylic acid (CAS 69647-59-2) is a high-purity analytical reference standard with the molecular formula C8H12O4 and a molecular weight of 172.18 g/mol.

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.
