Chemical Structure
Description
The occurrence of Dibromobis(triphenylphosphine)iron is closely related to a salt form, organophosphorus functionality, bromine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Dibromobis(triphenylphosphine)iron (CAS 19543-99-8), molecular formula C36H30Br2FeP2 and molecular weight 740.22 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a salt form, organophosphorus functionality, bromine substitution, a polycyclic aromatic system, Dibromobis(triphenylphosphine)iron is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 740.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
