Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Tris(2,4-Dibromo-phenyl)phosphate.
Tris(2,4-Dibromo-phenyl)phosphate (CAS 49690-63-3) is a high-purity analytical reference standard with the molecular formula C18H9Br6O4P and a molecular weight of 799.66 g/mol.
Owing to a flavonoid core, a phosphate ester group, a hydroxyl group, an ether linkage, bromine substitution, Tris(2,4-Dibromo-phenyl)phosphate is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 799.66 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
