Chemical Structure

(Triethylsilyl)acetylene CAS 1777-03-3 chemical structure

Description

(Triethylsilyl)acetylene (CAS 1777-03-3), molecular formula C8H16Si and molecular weight 140.30 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (Triethylsilyl)acetylene (C8H16Si) contains an organic framework. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 140.30 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.
