(4aR,5aS)-Ethyl 5a-methyl-1,4,4a,5,5a,6-hexahydrocyclopropa[f]indazole-3-carboxylate (CAS 2655557-59-6), molecular formula C12H16N2O2 and molecular weight 220.27 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (4aR,5aS)-Ethyl 5a-methyl-1,4,4a,5,5a,6-hexahydrocyclopropa[f]indazole-3-carboxylate (C12H16N2O2) 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 its high hydrophobicity (logP), 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.
