Chemical Structure
Description
1-((5-Bromothiophen-2-yl)sulfonyl)-2-methylpiperidine (CAS 897449-94-4) is a high-purity analytical reference standard with the molecular formula C10H14BrNO2S2 and a molecular weight of 324.26 g/mol.
Structurally, 1-((5-Bromothiophen-2-yl)sulfonyl)-2-methylpiperidine (C10H14BrNO2S2) 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 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 324.26 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
