Chemical Structure
Description
The occurrence of 5-(Benzo[d][1,3]dioxol-5-yl)-1H-pyrazol-3-amine is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-(Benzo[d][1,3]dioxol-5-yl)-1H-pyrazol-3-amine (CAS 208519-15-7), molecular formula C10H9N3O2 and molecular weight 203.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-(Benzo[d][1,3]dioxol-5-yl)-1H-pyrazol-3-amine (C10H9N3O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
