Chemical Structure

1,2,4-Trimethylcyclopentadienyl zirconiumtrichloride CAS 188020-78-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,2,4-Trimethylcyclopentadienyl zirconiumtrichloride.

1,2,4-Trimethylcyclopentadienyl zirconiumtrichloride (CAS 188020-78-2), molecular formula C8H11ZrCl and molecular weight 233.85 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1,2,4-Trimethylcyclopentadienyl zirconiumtrichloride (C8H11ZrCl) is characterized by chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
