Chemical Structure
Description
The occurrence of 2-Cyano-3,11-dioxo-18�-oleana-1,12-dien-30-oic acid methyl ester 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.
2-Cyano-3,11-dioxo-18�-oleana-1,12-dien-30-oic acid methyl ester (CAS 944832-18-2) is a high-purity analytical reference standard with the molecular formula C32H43NO4 and a molecular weight of 505.69 g/mol.
2-Cyano-3,11-dioxo-18�-oleana-1,12-dien-30-oic acid methyl ester (C32H43NO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 2-Cyano-3,11-dioxo-18�-oleana-1,12-dien-30-oic acid methyl ester under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
