Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Fluorophenethylzinc bromide.
3-Fluorophenethylzinc bromide (CAS 1142275-36-2), molecular formula C8H8BrFZn and molecular weight 268.46 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C8H8BrFZn, 3-Fluorophenethylzinc bromide contains a salt form, fluorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 268.46 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
