Chemical Structure
Description
5-Methyl-2-oxo-1,3-dioxole-4-carboxylic Acid (CAS 478297-08-4), molecular formula C5H4O5 and molecular weight 144.08 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carbohydrate-derived structure, 5-Methyl-2-oxo-1,3-dioxole-4-carboxylic Acid is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 144.08 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
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.
