Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Holmium(III) iodide (CAS 13813-41-7) is a high-purity analytical reference standard with the molecular formula C50H68N5O10P and a molecular weight of 930.08 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, Holmium(III) iodide is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 930.08 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
