1-[(5-Bromo-2-methyl-4-methylsulfonyl)phenyl]-piperazine CAS 1000018-35-8

Description

Based on its molecular formula C12H17BrN2O2S, 1-[(5-Bromo-2-methyl-4-methylsulfonyl)phenyl]-piperazine contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 333.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

1-[(5-Bromo-2-methyl-4-methylsulfonyl)phenyl]-piperazine (CAS 1000018-35-8), molecular formula C12H17BrN2O2S and molecular weight 333.24 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.
