2,5-Bis((trimethylsilyl)ethynyl)thiophene CAS 79109-69-6

Description

The occurrence of 2,5-Bis((trimethylsilyl)ethynyl)thiophene is closely related to sulfur-containing functionality, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2,5-Bis((trimethylsilyl)ethynyl)thiophene (CAS 79109-69-6), a certified reference material (molecular formula C14H20SSi2, MW 276.54 g/mol) for analytical method development and quality control.

Structurally, 2,5-Bis((trimethylsilyl)ethynyl)thiophene (C14H20SSi2) contains sulfur-containing functionality, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 276.54 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

As a certified reference material (CRM), 2,5-Bis((trimethylsilyl)ethynyl)thiophene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
