Chemical Structure

a-Styrenylmagnesium bromide 0.5 M in Tetrahydrofuran CAS 67300-99-6 chemical structure

Description

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

CATO supplies a-Styrenylmagnesium bromide 0.5 M in Tetrahydrofuran (CAS 67300-99-6), a certified reference material (molecular formula C8H7BrMg, MW 207.35 g/mol) for analytical method development and quality control.

a-Styrenylmagnesium bromide 0.5 M in Tetrahydrofuran (C8H7BrMg) 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).

As a certified reference material (CRM), a-Styrenylmagnesium bromide 0.5 M in Tetrahydrofuran 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.
