Description

Compared with other compounds in its class, the molecular weight of 258.28 g/mol gives 1,4-Bis((1H-pyrazol-4-yl)ethynyl)benzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1,4-Bis((1H-pyrazol-4-yl)ethynyl)benzene (CAS 1616862-09-9), a certified reference material (molecular formula C16H10N4, MW 258.28 g/mol) for analytical method development and quality control.

Based on its molecular formula C16H10N4, 1,4-Bis((1H-pyrazol-4-yl)ethynyl)benzene contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 258.28 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
