Chemical Structure
Description
CATO supplies Pyridin-4-ylmagnesium bromide, 0.25M THF (CAS 21970-15-0), a certified reference material (molecular formula C5H4BrMgN, MW 182.30 g/mol) for analytical method development and quality control.
Pyridin-4-ylmagnesium bromide, 0.25M THF (C5H4BrMgN) contains a salt form, a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 Pyridin-4-ylmagnesium bromide, 0.25M THF 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.
