Chemical Structure
Description
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.
3-(3-Bromo-5-methylthiophen-2-yl)-3-methylbutan-1-amine (CAS 1542556-57-9) is a high-purity analytical reference standard with the molecular formula C10H16BrNS and a molecular weight of 262.21 g/mol.
The molecular framework of 3-(3-Bromo-5-methylthiophen-2-yl)-3-methylbutan-1-amine (C10H16BrNS) is characterized by a nitrile group, sulfur-containing functionality, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
