Chemical Structure
Description
Structurally, Bis(1,3-dimethylcyclopenta-2,4-dien-1-yl)zirconium(IV) chloride (C14H18ZrCl) 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 312.97 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.
Bis(1,3-dimethylcyclopenta-2,4-dien-1-yl)zirconium(IV) chloride (CAS 119445-92-0), molecular formula C14H18ZrCl and molecular weight 312.97 g/mol, is a CATO reference standard with documented purity and traceability.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
