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 4-Benzoyl-2-methyl-1-[(7-oxido-1h-pyrrolo[2,3-b]pyridin-3-yl)oxoacetyl]-piperazine.
4-Benzoyl-2-methyl-1-[(7-oxido-1h-pyrrolo[2,3-b]pyridin-3-yl)oxoacetyl]-piperazine (CAS 357262-90-9) is a high-purity analytical reference standard with the molecular formula C21H20N4O4 and a molecular weight of 392.41 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 4-Benzoyl-2-methyl-1-[(7-oxido-1h-pyrrolo[2,3-b]pyridin-3-yl)oxoacetyl]-piperazine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 392.41 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
