Chemical Structure

a-Styrenylzinc bromide CAS 151073-86-8 chemical structure

Description

As a certified reference material (CRM), a-Styrenylzinc bromide 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.

a-Styrenylzinc bromide (CAS 151073-86-8) is a high-purity analytical reference standard with the molecular formula C8H7BrZn and a molecular weight of 248.45 g/mol.

Owing to a salt form, bromine substitution, an aromatic ring system, a-Styrenylzinc bromide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 248.45 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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