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.
CATO supplies m-Samarium oxalate (CAS 3252-68-4), a certified reference material (molecular formula SmC2O4, MW 238.38 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, an ether linkage, m-Samarium oxalate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 238.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
