Description
As a certified reference material (CRM), 3-(1,3-Benzodioxol-5-yl)-1H-pyrazole-5-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.
3-(1,3-Benzodioxol-5-yl)-1H-pyrazole-5-carboxylic acid (CAS 890621-48-4) is a high-purity analytical reference standard with the molecular formula C11H8N2O4 and a molecular weight of 232.19 g/mol.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 3-(1,3-Benzodioxol-5-yl)-1H-pyrazole-5-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 232.19 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.
