Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 128.08 g/mol gives 2-hydroxyfuran-3-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-hydroxyfuran-3-carboxylic acid (CAS 2170788-48-2), molecular formula C5H4O4 and molecular weight 128.08 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carbohydrate-derived structure, 2-hydroxyfuran-3-carboxylic acid is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 128.08 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.
As a certified reference material (CRM), 2-hydroxyfuran-3-carboxylic 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.
