Li Standard Solution CAS 7439-93-2 chemical structure

Description

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

CATO supplies Li Standard Solution (CAS 7439-93-2), a certified reference material (molecular formula Li, MW 6.94 g/mol) for analytical method development and quality control.

Owing to an inorganic composition, Li Standard Solution is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 6.94 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
