Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 418.36 g/mol gives Tributyl(4-nitrobenzyl)phosphonium bromide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Tributyl(4-nitrobenzyl)phosphonium bromide (CAS 6140-98-3) is a high-purity analytical reference standard with the molecular formula C19H33NO2PBr and a molecular weight of 418.36 g/mol.
Owing to an amide group, organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, Tributyl(4-nitrobenzyl)phosphonium bromide is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 418.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), Tributyl(4-nitrobenzyl)phosphonium bromide 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.
