Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,3,5-Tribromo-2,4,6-trimethylbenzene.
1,3,5-Tribromo-2,4,6-trimethylbenzene (CAS 608-72-0) is a high-purity analytical reference standard with the molecular formula C9H9Br3 and a molecular weight of 356.88 g/mol.
The molecular framework of 1,3,5-Tribromo-2,4,6-trimethylbenzene (C9H9Br3) is characterized by bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
