Chemical Structure

Tris(N,N-bis(trimethylsilyl)amide)lanthanum(III) CAS 35788-99-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Tris(N,N-bis(trimethylsilyl)amide)lanthanum(III).

Tris(N,N-bis(trimethylsilyl)amide)lanthanum(III) (CAS 35788-99-9), molecular formula C18H54LaN3Si6 and molecular weight 620.06 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Tris(N,N-bis(trimethylsilyl)amide)lanthanum(III) (C18H54LaN3Si6) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

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.
