1-Bromo-4-methyl-9h-thioxanthen-9-one CAS 1859087-87-8

Description

Compared with other compounds in its class, the molecular weight of 305.19 g/mol gives 1-Bromo-4-methyl-9h-thioxanthen-9-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-Bromo-4-methyl-9h-thioxanthen-9-one (CAS 1859087-87-8) is a high-purity analytical reference standard with the molecular formula C14H9BrOS and a molecular weight of 305.19 g/mol.

The molecular framework of 1-Bromo-4-methyl-9h-thioxanthen-9-one (C14H9BrOS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system. 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.

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.
