The molecular framework of CI 898 D-Glucuronic Acid Salt (Trimetrexate D-Glucuronic Acid Salt) (C19H23N5O3C6H10O7) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CI 898 D-Glucuronic Acid Salt (Trimetrexate D-Glucuronic Acid Salt) (CAS 82952-64-5), molecular formula C19H23N5O3C6H10O7 and molecular weight 563.56 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
