Hexamethyldisilane CAS 1450-14-2 chemical structure

Description

Hexamethyldisilane (CAS 1450-14-2), molecular formula C6H18Si2 and molecular weight 146.38 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Hexamethyldisilane (C6H18Si2) contains an organic framework. The molecule exhibits a degree of unsaturation (DBE) of -2.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 146.38 g/mol, it falls into the low-molecular-weight range.

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.
