5-Bromo-2,3,4,6-tetramethyl-2,3-dihydrobenzofuran CAS 667466-08-2

Description

The occurrence of 5-Bromo-2,3,4,6-tetramethyl-2,3-dihydrobenzofuran is closely related to 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.

5-Bromo-2,3,4,6-tetramethyl-2,3-dihydrobenzofuran (CAS 667466-08-2), molecular formula C12H15BrO and molecular weight 255.15 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-Bromo-2,3,4,6-tetramethyl-2,3-dihydrobenzofuran (C12H15BrO) is characterized by a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 5-Bromo-2,3,4,6-tetramethyl-2,3-dihydrobenzofuran 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.
