Chemical Structure
Description
3-Quinuclidinylxanthene-9-carboxylic acid hemioxalate salt (CAS 82326-74-7), molecular formula C21H21NO3C2H2O4 and molecular weight 425.44 g/mol, is a CATO reference standard with documented purity and traceability.
3-Quinuclidinylxanthene-9-carboxylic acid hemioxalate salt (C21H21NO3C2H2O4) contains a flavonoid core, 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 3-Quinuclidinylxanthene-9-carboxylic acid hemioxalate salt 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.
