Description

Compared with other compounds in its class, the molecular weight of 317.99 g/mol gives 4-Bromo-2-chloro-1-(4-chlorophenoxy)benzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Bromo-2-chloro-1-(4-chlorophenoxy)benzene (CAS 137736-65-3), molecular formula C12H7BrCl2O and molecular weight 317.99 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4-Bromo-2-chloro-1-(4-chlorophenoxy)benzene (C12H7BrCl2O) contains a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 317.99 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
