The occurrence of 2-(Bromomethyl)-2-(4-chlorophenyl)-1,3-dioxolane is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(Bromomethyl)-2-(4-chlorophenyl)-1,3-dioxolane (CAS 3418-24-4) is a high-purity analytical reference standard with the molecular formula C10H10BrClO2 and a molecular weight of 277.54 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system, 2-(Bromomethyl)-2-(4-chlorophenyl)-1,3-dioxolane is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 277.54 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
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.
