Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 312.10 g/mol gives 3-Bromo-2-methyl-5-(pentafluorothio)aniline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Bromo-2-methyl-5-(pentafluorothio)aniline (CAS 1373920-91-2) is a high-purity analytical reference standard with the molecular formula C7H7BrF5NS and a molecular weight of 312.10 g/mol.
The molecular framework of 3-Bromo-2-methyl-5-(pentafluorothio)aniline (C7H7BrF5NS) is characterized by a nitrile group, sulfur-containing functionality, fluorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
