Chemical Structure

2-Ethylphenylmagnesium bromide, 0.5M THF CAS 21450-63-5 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Ethylphenylmagnesium bromide, 0.5M THF.

2-Ethylphenylmagnesium bromide, 0.5M THF (CAS 21450-63-5) is a high-purity analytical reference standard with the molecular formula C8H9BrMg and a molecular weight of 209.37 g/mol.

2-Ethylphenylmagnesium bromide, 0.5M THF (C8H9BrMg) contains a salt form, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 2-Ethylphenylmagnesium bromide, 0.5M THF 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.
