Chemical Structure
Description
The occurrence of 3-Fluoro-2,5-dimethylpyrazine is closely related to a nitrile group, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3-Fluoro-2,5-dimethylpyrazine (CAS 33870-93-8), a certified reference material (molecular formula C6H7FN2, MW 126.13 g/mol) for analytical method development and quality control.
Owing to a nitrile group, fluorine substitution, an aromatic ring system, 3-Fluoro-2,5-dimethylpyrazine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 126.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
