Chemical Structure

Potassium 5-bromopyridine-3-trifluoroborate CAS 1239437-45-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 224.79 g/mol gives Potassium 5-bromopyridine-3-trifluoroborate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Potassium 5-bromopyridine-3-trifluoroborate (CAS 1239437-45-6), molecular formula C5H3BBrF3N and molecular weight 224.79 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Potassium 5-bromopyridine-3-trifluoroborate (C5H3BBrF3N) contains a nitrile group, fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 224.79 g/mol, it falls into the medium-molecular-weight range. 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).

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.

As a certified reference material (CRM), Potassium 5-bromopyridine-3-trifluoroborate 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.
