Chemical Structure

Tb Standard Solution CAS 7440-27-9 chemical structure

Description

The occurrence of Tb Standard Solution is closely related to an inorganic composition in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Tb Standard Solution (CAS 7440-27-9), molecular formula Tb and molecular weight 158.93 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an inorganic composition, Tb Standard Solution is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 158.93 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
