Description

Compared with other compounds in its class, the molecular weight of 363.27 g/mol gives 1-((3-Bromo-4-methoxyphenyl)sulfonyl)-4-ethylpiperazine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-((3-Bromo-4-methoxyphenyl)sulfonyl)-4-ethylpiperazine (CAS 677303-98-9), molecular formula C13H19BrN2O3S and molecular weight 363.27 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1-((3-Bromo-4-methoxyphenyl)sulfonyl)-4-ethylpiperazine (C13H19BrN2O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 363.27 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
