Dichlorobis[(1,2,3,4,5-η)-1-(1,1-dimethylethyl)-2,4-cyclopentadien-1-yl]hafnium CAS 33010-55-8

Description

As a certified reference material (CRM), Dichlorobis[(1,2,3,4,5-η)-1-(1,1-dimethylethyl)-2,4-cyclopentadien-1-yl]hafnium 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.

Dichlorobis[(1,2,3,4,5-η)-1-(1,1-dimethylethyl)-2,4-cyclopentadien-1-yl]hafnium (CAS 33010-55-8) is a high-purity analytical reference standard with the molecular formula C18H26Cl2Hf and a molecular weight of 491.80 g/mol.

Structurally, Dichlorobis[(1,2,3,4,5-η)-1-(1,1-dimethylethyl)-2,4-cyclopentadien-1-yl]hafnium (C18H26Cl2Hf) contains chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 491.80 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.

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.
