Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(4-Amino-5-(4-methoxyphenyl)-1H-pyrazol-1-yl)ethanol (CAS 1707375-28-7), molecular formula C12H15N3O2 and molecular weight 233.27 g/mol, is a CATO reference standard with documented purity and traceability.
2-(4-Amino-5-(4-methoxyphenyl)-1H-pyrazol-1-yl)ethanol (C12H15N3O2) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
