Description
As a certified reference material (CRM), 855-38-9 Phosphine, tris(4-methoxyphenyl)- Tris(4-methoxyphenyl)phosphine AI3-62578 EINECS 212-723-0 NSC 136458 Phosphine, tris(p-methoxyphenyl)- Trianisylphosphine Tri-p-anisylphosphine Tris(p-anisyl)phosphine tris(p-Methoxyphenyl)phosphine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
855-38-9 Phosphine, tris(4-methoxyphenyl)- Tris(4-methoxyphenyl)phosphine AI3-62578 EINECS 212-723-0 NSC 136458 Phosphine, tris(p-methoxyphenyl)- Trianisylphosphine Tri-p-anisylphosphine Tris(p-anisyl)phosphine tris(p-Methoxyphenyl)phosphine (CAS 855-38-9) is a high-purity analytical reference standard with the molecular formula C21H39O3P and a molecular weight of 370.51 g/mol.
Based on its molecular formula C21H39O3P, 855-38-9 Phosphine, tris(4-methoxyphenyl)- Tris(4-methoxyphenyl)phosphine AI3-62578 EINECS 212-723-0 NSC 136458 Phosphine, tris(p-methoxyphenyl)- Trianisylphosphine Tri-p-anisylphosphine Tris(p-anisyl)phosphine tris(p-Methoxyphenyl)phosphine contains a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 370.51 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
