Chemical Structure
Description
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.
(2-Bromo-3-chloro-5-iodophenyl)methanol (CAS 2092867-48-4), molecular formula C7H5BrClIO and molecular weight 347.38 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (2-Bromo-3-chloro-5-iodophenyl)methanol (C7H5BrClIO) contains a hydroxyl group, an ether linkage, chlorine/bromine/iodine 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 347.38 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
