Chemical Structure
Description
The occurrence of 4-Methoxybromobenzyl (Containing 5% Potassium Carbonate Stabilizer) is closely related to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Methoxybromobenzyl (Containing 5% Potassium Carbonate Stabilizer) (CAS 2746-25-0) is a high-purity analytical reference standard with the molecular formula C8H9BrO and a molecular weight of 201.06 g/mol.
Structurally, 4-Methoxybromobenzyl (Containing 5% Potassium Carbonate Stabilizer) (C8H9BrO) contains a hydroxyl group, an ether linkage, 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 201.06 g/mol, it falls into the medium-molecular-weight range. 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.
