Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 898.64 g/mol gives Pentagalacturonic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Pentagalacturonic Acid (CAS 40386-94-5) is a high-purity analytical reference standard with the molecular formula C30H42O31 and a molecular weight of 898.64 g/mol.
Based on its molecular formula C30H42O31, Pentagalacturonic Acid contains a carboxylic acid group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 898.64 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
As a certified reference material (CRM), Pentagalacturonic Acid 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.
