Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-methyl-1-(oxan-4-yl)-1H-pyrazole-5-carboxylic acid (CAS 1369357-49-2), molecular formula C10H14N2O3 and molecular weight 210.23 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 3-methyl-1-(oxan-4-yl)-1H-pyrazole-5-carboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 210.23 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).
CATO manufactures 3-methyl-1-(oxan-4-yl)-1H-pyrazole-5-carboxylic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
