Chemical Structure

Pyridin-2-ylmagnesium bromide, 0.25 M in THF CAS 21970-13-8 chemical structure

Description

The occurrence of Pyridin-2-ylmagnesium bromide, 0.25 M in THF is closely related to a salt form, a nitrile group, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Pyridin-2-ylmagnesium bromide, 0.25 M in THF (CAS 21970-13-8) is a high-purity analytical reference standard with the molecular formula BrC5H4NMg and a molecular weight of 182.30 g/mol.

Owing to a salt form, a nitrile group, bromine substitution, Pyridin-2-ylmagnesium bromide, 0.25 M in THF is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 182.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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-2-ylmagnesium bromide, 0.25 M in 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.
