Chemical Structure
Description
Osmium dodecacarbonyl (CAS 15696-40-9), molecular formula OsCO and molecular weight 218.24 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Osmium dodecacarbonyl (OsCO) contains a hydroxyl group. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 218.24 g/mol, it falls into the medium-molecular-weight range.
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.
