Chemical Structure

4-bromo-1,5-dimethyl-1H-indazole CAS 1159511-77-9 chemical structure

Description

Owing to a nitrile group, bromine substitution, 4-bromo-1,5-dimethyl-1H-indazole is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 233.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

4-bromo-1,5-dimethyl-1H-indazole (CAS 1159511-77-9), molecular formula C9H17BrN2 and molecular weight 233.15 g/mol, is a CATO reference standard with documented purity and traceability.

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.
