The molecular framework of 2085-33-8 8-Hydroxyquinoline aluminum salt Alq3 Alq3, Aluminum 8-hydroxyquinolinatt Aluminum 8-hydroxyquinolinate Aluminum oxinate Aluminum oxinate, Tris(8-hydroxyquinolinato)aluminium Tris-(8-hydroxyquinolinato)aluminum Tris-(8-hydroxyquinoline)aluminum (C27H48AlN3O3) is characterized by a steroid 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
