Chemical Structure
Description
Owing to an organic framework, 碳酸锂-<SUP>7</SUP>Li is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 66.95 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
CATO supplies 碳酸锂-<SUP>7</SUP>Li (CAS 71552-93-7), a certified reference material (molecular formula CO3 2*[7Li], MW 66.95 g/mol) for analytical method development and quality control.
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.
