Description
As a certified reference material (CRM), 1-BROMO-2,4,6-TRI-TERT-BUTYLBENZENE 2,4,6-Tri-tert-butylbromobenzene 2-BROMO-1,3,5-TRI-TERT-BUTYLBENZENE 3975-77-7 AS05740 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.
1-BROMO-2,4,6-TRI-TERT-BUTYLBENZENE 2,4,6-Tri-tert-butylbromobenzene 2-BROMO-1,3,5-TRI-TERT-BUTYLBENZENE 3975-77-7 AS05740 (CAS 3975-77-7) is a high-purity analytical reference standard with the molecular formula C18H35Br and a molecular weight of 331.37 g/mol.
The molecular framework of 1-BROMO-2,4,6-TRI-TERT-BUTYLBENZENE 2,4,6-Tri-tert-butylbromobenzene 2-BROMO-1,3,5-TRI-TERT-BUTYLBENZENE 3975-77-7 AS05740 (C18H35Br) is characterized by bromine substitution. 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.
