Chemical Structure
Description
The occurrence of Bis(1-ethyl-3-methylcyclopentadienyl)zirconiumdichloride is closely related to chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Bis(1-ethyl-3-methylcyclopentadienyl)zirconiumdichloride (CAS 73364-11-1), a certified reference material (molecular formula C16H22ZrCl, MW 341.03 g/mol) for analytical method development and quality control.
Structurally, Bis(1-ethyl-3-methylcyclopentadienyl)zirconiumdichloride (C16H22ZrCl) contains chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.5, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 341.03 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.
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.
