Ethyl (1R,2R)-2'-oxospiro[cyclopropane-1,3'-indoline]-2-carboxylate CAS 67487-95-0

Description

The occurrence of Ethyl (1R,2R)-2'-oxospiro[cyclopropane-1,3'-indoline]-2-carboxylate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ethyl (1R,2R)-2'-oxospiro[cyclopropane-1,3'-indoline]-2-carboxylate (CAS 67487-95-0), molecular formula C13H13NO3 and molecular weight 231.25 g/mol, is a CATO reference standard with documented purity and traceability.

Ethyl (1R,2R)-2'-oxospiro[cyclopropane-1,3'-indoline]-2-carboxylate (C13H13NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
