Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 258.13 g/mol gives (S)-2-(2-bromo-4-fluoro-5-methylphenyl)pyrrolidine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(S)-2-(2-bromo-4-fluoro-5-methylphenyl)pyrrolidine (CAS 1272744-91-8) is a high-purity analytical reference standard with the molecular formula C11H13BrFN and a molecular weight of 258.13 g/mol.
(S)-2-(2-bromo-4-fluoro-5-methylphenyl)pyrrolidine (C11H13BrFN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (S)-2-(2-bromo-4-fluoro-5-methylphenyl)pyrrolidine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
