2-[(1-methyl-1h-pyrazol-5-yl)methoxy]acetic acid (CAS 1173076-45-3), molecular formula C7H10N2O3 and molecular weight 170.17 g/mol, is a CATO reference standard with documented purity and traceability.
2-[(1-methyl-1h-pyrazol-5-yl)methoxy]acetic acid (C7H10N2O3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 2-[(1-methyl-1h-pyrazol-5-yl)methoxy]acetic 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.
