Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

1-(2-Methoxyphenyl)-4-methyl-1,6-dihydro-7h-pyrazolo[3,4-d]pyridazin-7-on+ (CAS 1105197-91-8), molecular formula C13H12N4O2 and molecular weight 256.26 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 1-(2-Methoxyphenyl)-4-methyl-1,6-dihydro-7h-pyrazolo[3,4-d]pyridazin-7-on+ is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 256.26 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.

As a certified reference material (CRM), 1-(2-Methoxyphenyl)-4-methyl-1,6-dihydro-7h-pyrazolo[3,4-d]pyridazin-7-on+ 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.
