Chemical Structure
Description
Based on its molecular formula CH2O2CHO2K, Potassium biformate 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 130.14 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.
Potassium biformate (CAS 20642-05-1), molecular formula CH2O2CHO2K and molecular weight 130.14 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
