Chemical Structure

1-(3-Chlorophenyl)-4-cyclopropyl-1,6-dihydro-7H-pyrazolo[3,4-d]pyridazin-7-one CAS 1105197-33-8 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 1-(3-Chlorophenyl)-4-cyclopropyl-1,6-dihydro-7H-pyrazolo[3,4-d]pyridazin-7-one.

CATO supplies 1-(3-Chlorophenyl)-4-cyclopropyl-1,6-dihydro-7H-pyrazolo[3,4-d]pyridazin-7-one (CAS 1105197-33-8), a certified reference material (molecular formula C14H11ClN4O, MW 286.72 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, chlorine substitution, 1-(3-Chlorophenyl)-4-cyclopropyl-1,6-dihydro-7H-pyrazolo[3,4-d]pyridazin-7-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 286.72 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.
