Chemical Structure

Ethanol, polymer with tantalum chloride (TaCl5) CAS 135929-42-9 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.

Ethanol, polymer with tantalum chloride (TaCl5) (CAS 135929-42-9), molecular formula Cl5TaC2H6O and molecular weight 404.27 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula Cl5TaC2H6O, Ethanol, polymer with tantalum chloride (TaCl5) contains a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 404.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
