6-(4-Bromophenyl)-1,4,5,7-tetramethyl-6H-pyrrolo[3,4-d]pyridazine CAS 461431-55-0

Description

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.

6-(4-Bromophenyl)-1,4,5,7-tetramethyl-6H-pyrrolo[3,4-d]pyridazine (CAS 461431-55-0), molecular formula C16H16BrN3 and molecular weight 330.22 g/mol, is a CATO reference standard with documented purity and traceability.

6-(4-Bromophenyl)-1,4,5,7-tetramethyl-6H-pyrrolo[3,4-d]pyridazine (C16H16BrN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
