Chemical Structure

2-Bromooctane CAS 557-35-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 193.12 g/mol gives 2-Bromooctane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-Bromooctane (CAS 557-35-7), a certified reference material (molecular formula C8H17Br, MW 193.12 g/mol) for analytical method development and quality control.

The molecular framework of 2-Bromooctane (C8H17Br) is characterized by bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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.

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.
