Chemical Structure

1,2-Diethynyl-3,4,5,6-tetramethylbenzene CAS 65103-79-9 chemical structure

Description

CATO supplies 1,2-Diethynyl-3,4,5,6-tetramethylbenzene (CAS 65103-79-9), a certified reference material (molecular formula C14H14, MW 182.26 g/mol) for analytical method development and quality control.

Based on its molecular formula C14H14, 1,2-Diethynyl-3,4,5,6-tetramethylbenzene contains a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 182.26 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

CATO manufactures 1,2-Diethynyl-3,4,5,6-tetramethylbenzene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
