Chemical Structure
Description
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.
Dichloro(tri-o-tolyl)bismuth (CAS 6729-60-8) is a high-purity analytical reference standard with the molecular formula C21H21BiCl2 and a molecular weight of 553.28 g/mol.
Structurally, Dichloro(tri-o-tolyl)bismuth (C21H21BiCl2) contains chlorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 10.5, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 553.28 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
