Chemical Structure
Description
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.
Calcium lanthanum sulfide (CAS 12525-03-0), molecular formula CaLa2S4 and molecular weight 446.15 g/mol, is a CATO reference standard with documented purity and traceability.
Calcium lanthanum sulfide (CaLa2S4) contains sulfur-containing functionality. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions.
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.
