2-Methyl-1H-benzo[4,5]imidazo[1,2-b]pyrazole-6-sulfonic acid CAS 439092-52-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Methyl-1H-benzo[4,5]imidazo[1,2-b]pyrazole-6-sulfonic acid.

2-Methyl-1H-benzo[4,5]imidazo[1,2-b]pyrazole-6-sulfonic acid (CAS 439092-52-1), molecular formula C10H9N3O3S and molecular weight 251.26 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-Methyl-1H-benzo[4,5]imidazo[1,2-b]pyrazole-6-sulfonic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 251.26 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.
