5,7-Dimethyl-6H-pyrrolo[3,4-d]pyridazine CAS 59718-12-6

Description

The occurrence of 5,7-Dimethyl-6H-pyrrolo[3,4-d]pyridazine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5,7-Dimethyl-6H-pyrrolo[3,4-d]pyridazine (CAS 59718-12-6) is a high-purity analytical reference standard with the molecular formula C8H9N3 and a molecular weight of 147.18 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 5,7-Dimethyl-6H-pyrrolo[3,4-d]pyridazine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 147.18 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
