Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 454.67 g/mol gives Tris(4-methoxy-3,5-dimethylphenyl)phosphine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Tris(4-methoxy-3,5-dimethylphenyl)phosphine (CAS 121898-64-4), a certified reference material (molecular formula C27H51O3P, MW 454.67 g/mol) for analytical method development and quality control.
Tris(4-methoxy-3,5-dimethylphenyl)phosphine (C27H51O3P) contains a phosphonate group, a carboxylic acid 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.
As a certified reference material (CRM), Tris(4-methoxy-3,5-dimethylphenyl)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.
