Chemical Structure
Description
The occurrence of 1,6-Bis(trimethylsilyl)hexa-1,3,5-triyne is closely related to an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1,6-Bis(trimethylsilyl)hexa-1,3,5-triyne (CAS 21752-86-3), a certified reference material (molecular formula C12H18Si2, MW 218.44 g/mol) for analytical method development and quality control.
The molecular framework of 1,6-Bis(trimethylsilyl)hexa-1,3,5-triyne (C12H18Si2) is characterized by an aromatic ring system. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
