Chemical Structure

Potassium hydrogen oxalate CAS 127-95-7 chemical structure

Description

The occurrence of Potassium hydrogen oxalate is closely related to a carboxylic acid group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Potassium hydrogen oxalate (CAS 127-95-7) is a high-purity analytical reference standard with the molecular formula C2H2O4K and a molecular weight of 129.13 g/mol.

Structurally, Potassium hydrogen oxalate (C2H2O4K) contains a carboxylic acid group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 129.13 g/mol, it falls into the low-molecular-weight range.

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), Potassium hydrogen oxalate 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.
