Chemical Structure
Description
Structurally, Methyl-d3-triphenylphosphonium Bromide (C19H15D3PBr) contains deuterium isotope labeling, organophosphorus functionality, bromine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 360.25 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Methyl-d3-triphenylphosphonium Bromide (CAS 1787-44-6) is a high-purity analytical reference standard with the molecular formula C19H15D3PBr and a molecular weight of 360.25 g/mol.
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), Methyl-d3-triphenylphosphonium 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.
