Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(4,5-Diphenyl-1H-pyrazolo[3,4-c]pyridazin-3-yl)acetamide.
N-(4,5-Diphenyl-1H-pyrazolo[3,4-c]pyridazin-3-yl)acetamide (CAS 122505-71-9) is a high-purity analytical reference standard with the molecular formula C19H15N5O and a molecular weight of 329.36 g/mol.
N-(4,5-Diphenyl-1H-pyrazolo[3,4-c]pyridazin-3-yl)acetamide (C19H15N5O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
