Chemical Structure

Benzyl-α,α-d2 Bromide CAS 51271-29-5 chemical structure

Description

Benzyl-α,α-d2 Bromide (CAS 51271-29-5), molecular formula C7H5D2Br and molecular weight 173.05 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to deuterium isotope labeling, bromine substitution, an aromatic ring system, Benzyl-α,α-d2 Bromide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 173.05 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.

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), Benzyl-α,α-d2 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.
