Chemical Structure
Description
The occurrence of 1',3',3'-Trimethylspiro[chromene-2,2'-indolin]-6-ol is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1',3',3'-Trimethylspiro[chromene-2,2'-indolin]-6-ol (CAS 23001-29-8) is a high-purity analytical reference standard with the molecular formula C19H19NO2 and a molecular weight of 293.36 g/mol.
1',3',3'-Trimethylspiro[chromene-2,2'-indolin]-6-ol (C19H19NO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
