Chemical Structure

3,4-Dihydroxy-3-cyclobutene-1,2-dione CAS 2892-51-5 chemical structure

Description

The molecular framework of 3,4-Dihydroxy-3-cyclobutene-1,2-dione (C4H2O4) is characterized by a carbohydrate-derived structure. 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).

3,4-Dihydroxy-3-cyclobutene-1,2-dione (CAS 2892-51-5), molecular formula C4H2O4 and molecular weight 114.06 g/mol, is a CATO reference standard with documented purity and traceability.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
