Description
927XE902HL 137-99-5 2,4-Dinonylphenol Phenol, 2,4-dinonyl- EINECS 205-310-1 HSDB 5625 UNII-927XE902HL (CAS 137-99-5) is a high-purity analytical reference standard with the molecular formula C24H42O and a molecular weight of 346.59 g/mol.
927XE902HL 137-99-5 2,4-Dinonylphenol Phenol, 2,4-dinonyl- EINECS 205-310-1 HSDB 5625 UNII-927XE902HL (C24H42O) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
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.
