Chemical Structure
Description
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.
Tris(2-ethylhexyl) Phosphate-d51 (CAS 1259188-37-8), molecular formula C24D51O4P and molecular weight 485.95 g/mol, is a CATO reference standard with documented purity and traceability.
Tris(2-ethylhexyl) Phosphate-d51 (C24D51O4P) contains deuterium isotope labeling, a flavonoid core, a phosphate ester group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
