1,5-Dimethyl-3H-pyridazino[4,5-b]indol-4(5H)-one CAS 73918-70-4 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 1,5-Dimethyl-3H-pyridazino[4,5-b]indol-4(5H)-one.

1,5-Dimethyl-3H-pyridazino[4,5-b]indol-4(5H)-one (CAS 73918-70-4), molecular formula C12H11N3O and molecular weight 213.24 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1,5-Dimethyl-3H-pyridazino[4,5-b]indol-4(5H)-one (C12H11N3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 213.24 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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

CATO manufactures 1,5-Dimethyl-3H-pyridazino[4,5-b]indol-4(5H)-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
