Chemical Structure
Description
The occurrence of Lithium chromate dihydrate is closely related to an inorganic composition in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Lithium chromate dihydrate (CAS 7789-01-7), molecular formula H2CrO4H2OLi and molecular weight 142.96 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula H2CrO4H2OLi, Lithium chromate dihydrate contains an inorganic composition; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 142.96 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.
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.
