2,2-Dibromo-1-(3,5-dimethoxyphenyl)ethan-1-one CAS 188199-76-0

Description

The occurrence of 2,2-Dibromo-1-(3,5-dimethoxyphenyl)ethan-1-one is closely related to a carboxylic acid group, 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.

2,2-Dibromo-1-(3,5-dimethoxyphenyl)ethan-1-one (CAS 188199-76-0) is a high-purity analytical reference standard with the molecular formula C10H10Br2O3 and a molecular weight of 337.99 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 2,2-Dibromo-1-(3,5-dimethoxyphenyl)ethan-1-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 337.99 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

As a certified reference material (CRM), 2,2-Dibromo-1-(3,5-dimethoxyphenyl)ethan-1-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
