Chemical Structure

Butylmagnesium bromide CAS 693-03-8 chemical structure

Description

The occurrence of Butylmagnesium bromide is closely related to a salt form, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Butylmagnesium bromide (CAS 693-03-8) is a high-purity analytical reference standard with the molecular formula C4H9BrMg and a molecular weight of 161.32 g/mol.

Owing to a salt form, bromine substitution, Butylmagnesium bromide is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 161.32 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
