Lithium metaborate (LiBO2) is an inorganic compound primarily used as a flux in analytical chemistry for sample preparation, particularly in X-ray fluorescence (XRF) spectroscopy and inductively coupled plasma (ICP) analysis. It aids in dissolving silicate-based materials to enable accurate elemental quantification. CAS 13453-69-5, molecular weight 49.75 g/mol, requires ambient storage, and carries a danger signal word due to its corrosive and irritant properties. Molekula supplies lithium metaborate from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
