Chemical Structure
Description
The occurrence of 1,2,3-Tribromo-2-methylpropane is closely related to bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,2,3-Tribromo-2-methylpropane (CAS 631-28-7) is a high-purity analytical reference standard with the molecular formula C4H7Br3 and a molecular weight of 294.81 g/mol.
The molecular framework of 1,2,3-Tribromo-2-methylpropane (C4H7Br3) is characterized by bromine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
