Description
Compared with other compounds in its class, the molecular weight of 683.15 g/mol gives 9-(2-Carboxyphenyl)-2-chloro-5-[{2-(di(2-pyridyl)aminomethyl)phenyl}aminomethyl]-6-hydroxy-3-xanthanone Zinpyr-4 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
9-(2-Carboxyphenyl)-2-chloro-5-[{2-(di(2-pyridyl)aminomethyl)phenyl}aminomethyl]-6-hydroxy-3-xanthanone Zinpyr-4 (CAS 502467-23-4) is a high-purity analytical reference standard with the molecular formula C40H31ClN4O5 and a molecular weight of 683.15 g/mol.
The molecular framework of 9-(2-Carboxyphenyl)-2-chloro-5-[{2-(di(2-pyridyl)aminomethyl)phenyl}aminomethyl]-6-hydroxy-3-xanthanone Zinpyr-4 (C40H31ClN4O5) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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).
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.
