Chemical Structure
Description
16784-72-8 7KV2DH7E7A Tri(o-nonylphenyl) phosphite Phenol, 2-nonyl-, 1,1',1''-phosphite Phenol, 2-nonyl-, phosphite (3:1) o-Nonylphenol, phosphite (3:1) Tris(o-nonylphenyl) phosphite UNII-7KV2DH7E7A (C45H69O3P) contains a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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.
16784-72-8 7KV2DH7E7A Tri(o-nonylphenyl) phosphite Phenol, 2-nonyl-, 1,1',1''-phosphite Phenol, 2-nonyl-, phosphite (3:1) o-Nonylphenol, phosphite (3:1) Tris(o-nonylphenyl) phosphite UNII-7KV2DH7E7A (CAS 16784-72-8), molecular formula C45H69O3P and molecular weight 689.00 g/mol, is a CATO reference standard with documented purity and traceability.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 16784-72-8 7KV2DH7E7A Tri(o-nonylphenyl) phosphite Phenol, 2-nonyl-, 1,1',1''-phosphite Phenol, 2-nonyl-, phosphite (3:1) o-Nonylphenol, phosphite (3:1) Tris(o-nonylphenyl) phosphite UNII-7KV2DH7E7A 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.
