Chemical Structure

(2,6-Dibromo-4-methoxyphenyl)methanol CAS 1643918-95-9 chemical structure

Description

The occurrence of (2,6-Dibromo-4-methoxyphenyl)methanol 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.

(2,6-Dibromo-4-methoxyphenyl)methanol (CAS 1643918-95-9) is a high-purity analytical reference standard with the molecular formula C8H8Br2O2 and a molecular weight of 295.96 g/mol.

(2,6-Dibromo-4-methoxyphenyl)methanol (C8H8Br2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), (2,6-Dibromo-4-methoxyphenyl)methanol 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.
