Chemical Structure

Thulium(III) chloride hexahydrate CAS 13778-39-7 chemical structure

Description

Thulium(III) chloride hexahydrate (CAS 13778-39-7), molecular formula TmClH2O and molecular weight 222.40 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to chlorine substitution, Thulium(III) chloride hexahydrate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 222.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

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.
