Chemical Structure
Description
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.
2-(4-Methoxy-phenyl)-2,6-dihydro-4H-thieno[3,4-c]pyrazol-3-ylamine (CAS 214542-49-1), molecular formula C12H13N3OS and molecular weight 247.32 g/mol, is a CATO reference standard with documented purity and traceability.
2-(4-Methoxy-phenyl)-2,6-dihydro-4H-thieno[3,4-c]pyrazol-3-ylamine (C12H13N3OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
