Chemical Structure

6006-54-8 oxalacetic acid-anhydride CAS 6006-54-8 chemical structure

Description

As a certified reference material (CRM), 6006-54-8 oxalacetic acid-anhydride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

6006-54-8 oxalacetic acid-anhydride (CAS 6006-54-8) is a high-purity analytical reference standard with the molecular formula C4H2O4 and a molecular weight of 114.06 g/mol.

The molecular framework of 6006-54-8 oxalacetic acid-anhydride (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).

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.
