Chemical Structure
Description
The occurrence of 2,5-Bis(1,1-dimethylethyl)-pyrazine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,5-Bis(1,1-dimethylethyl)-pyrazine (CAS 18709-51-8) is a high-purity analytical reference standard with the molecular formula C12H20N2 and a molecular weight of 192.30 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 2,5-Bis(1,1-dimethylethyl)-pyrazine is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 192.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
