Chemical Structure

1-Ethyl-3-hydroxypyridinium bromide CAS 80866-84-8 chemical structure

Description

The occurrence of 1-Ethyl-3-hydroxypyridinium bromide is closely related to an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1-Ethyl-3-hydroxypyridinium bromide (CAS 80866-84-8), a certified reference material (molecular formula C7H10NOBr, MW 204.07 g/mol) for analytical method development and quality control.

Based on its molecular formula C7H10NOBr, 1-Ethyl-3-hydroxypyridinium bromide contains an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 204.07 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

CATO manufactures 1-Ethyl-3-hydroxypyridinium bromide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
