Chemical Structure

2-((Trimethylsilyl)ethynyl)thiazole CAS 113705-15-0 chemical structure

Description

2-((Trimethylsilyl)ethynyl)thiazole (CAS 113705-15-0) is a high-purity analytical reference standard with the molecular formula C8H11NSSi and a molecular weight of 181.33 g/mol.

Structurally, 2-((Trimethylsilyl)ethynyl)thiazole (C8H11NSSi) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 181.33 g/mol, it falls into the medium-molecular-weight range. 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.
