Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 340.09 g/mol gives 1-[(2-Bromo-4-chlorophenyl)methyl]-4-methylpiperazine dihydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1-[(2-Bromo-4-chlorophenyl)methyl]-4-methylpiperazine dihydrochloride (CAS 1881296-69-0), a certified reference material (molecular formula C12H16BrClN2HCl, MW 340.09 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution, 1-[(2-Bromo-4-chlorophenyl)methyl]-4-methylpiperazine dihydrochloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 340.09 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
