Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 163.00 g/mol gives 3,5-Dichloro-2-methylpyrazine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3,5-Dichloro-2-methylpyrazine (CAS 89284-38-8) is a high-purity analytical reference standard with the molecular formula C5H4Cl2N2 and a molecular weight of 163.00 g/mol.
Owing to a nitrile group, chlorine substitution, 3,5-Dichloro-2-methylpyrazine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 163.00 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
