5-Nitro-1-phenyl-1H-pyrazolo[3,4-b]pyridine-3-carbaldehyde CAS 88796-44-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Nitro-1-phenyl-1H-pyrazolo[3,4-b]pyridine-3-carbaldehyde.

CATO supplies 5-Nitro-1-phenyl-1H-pyrazolo[3,4-b]pyridine-3-carbaldehyde (CAS 88796-44-5), a certified reference material (molecular formula C13H8N4O3, MW 268.23 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 5-Nitro-1-phenyl-1H-pyrazolo[3,4-b]pyridine-3-carbaldehyde is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 268.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
