Chemical Structure
Description
Oxalic Acid Dihydrate (CAS 6153-56-6) is a high-purity analytical reference standard with the molecular formula C2H2O4H2O and a molecular weight of 108.05 g/mol.
Based on its molecular formula C2H2O4H2O, Oxalic Acid Dihydrate contains a carboxylic acid group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 108.05 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.
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), Oxalic Acid Dihydrate 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.
