CATO supplies 5-(5-Bromo-6-methoxynaphthalen-2-yl)-3-(3,4-dimethoxyphenyl)-6-methylpyrazolo[1,5-a]pyrimidine (CAS 866144-88-9), a certified reference material (molecular formula C26H22BrN3O3, MW 504.38 g/mol) for analytical method development and quality control.
The molecular framework of 5-(5-Bromo-6-methoxynaphthalen-2-yl)-3-(3,4-dimethoxyphenyl)-6-methylpyrazolo[1,5-a]pyrimidine (C26H22BrN3O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
