Chemical Structure

3-Methylbut-2-enylmagnesium chloride, 0.50 M in 2-MeTHF 35189-96-9 CAS 35189-96-9 chemical structure

Description

3-Methylbut-2-enylmagnesium chloride, 0.50 M in 2-MeTHF 35189-96-9 (C5H9ClMg) contains a salt form, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

CATO supplies 3-Methylbut-2-enylmagnesium chloride, 0.50 M in 2-MeTHF 35189-96-9 (CAS 35189-96-9), a certified reference material (molecular formula C5H9ClMg, MW 128.88 g/mol) for analytical method development and quality control.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
