Chemical Structure

N-hexylpyridinium bromide CAS 74440-81-6 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

N-hexylpyridinium bromide (CAS 74440-81-6) is a high-purity analytical reference standard with the molecular formula C11H18NBr and a molecular weight of 244.18 g/mol.

Based on its molecular formula C11H18NBr, N-hexylpyridinium bromide contains a nitrile group, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 244.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

As a certified reference material (CRM), N-hexylpyridinium bromide 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.
