Chemical Structure
Description
As a certified reference material (CRM), 4-Bromobenzylzinc bromide, 0.50 M in THF 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.
CATO supplies 4-Bromobenzylzinc bromide, 0.50 M in THF (CAS 115055-85-1), a certified reference material (molecular formula C7H6BrBrZn, MW 315.31 g/mol) for analytical method development and quality control.
Structurally, 4-Bromobenzylzinc bromide, 0.50 M in THF (C7H6BrBrZn) contains a salt form, bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 315.31 g/mol, it falls into the moderately-high-molecular-weight range. 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.
