6-Chloro-1-methyl-1H-pyrazolo[3,4-b]quinolin-4(9H)-one CAS 61689-23-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-Chloro-1-methyl-1H-pyrazolo[3,4-b]quinolin-4(9H)-one.

6-Chloro-1-methyl-1H-pyrazolo[3,4-b]quinolin-4(9H)-one (CAS 61689-23-4) is a high-purity analytical reference standard with the molecular formula C11H8ClN3O and a molecular weight of 233.65 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 6-Chloro-1-methyl-1H-pyrazolo[3,4-b]quinolin-4(9H)-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 233.65 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 6-Chloro-1-methyl-1H-pyrazolo[3,4-b]quinolin-4(9H)-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
