Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 631.51 g/mol gives Tris[N,N-bis(trimethylsilyl)amide]samarium(III) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Tris[N,N-bis(trimethylsilyl)amide]samarium(III) (CAS 35789-01-6), molecular formula C18H54N3Si6Sm and molecular weight 631.51 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Tris[N,N-bis(trimethylsilyl)amide]samarium(III) (C18H54N3Si6Sm) is characterized by an organic framework. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
