Description
CATO supplies 2-MEthyl-6,7,8,9-tetrahydro-5h-pyrazolo[1',5':1,2]pyrimido[4,5-d]azepin-10-ol dihydrochloride (CAS 1185533-39-4), a certified reference material (molecular formula C11H14N4OHCl, MW 254.72 g/mol) for analytical method development and quality control.
The molecular framework of 2-MEthyl-6,7,8,9-tetrahydro-5h-pyrazolo[1',5':1,2]pyrimido[4,5-d]azepin-10-ol dihydrochloride (C11H14N4OHCl) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
