2-Ethoxy-3-Methylpyrazine CAS 32737-14-7

Description

The occurrence of 2-Ethoxy-3-Methylpyrazine is closely related to an amide group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Ethoxy-3-Methylpyrazine (CAS 32737-14-7), molecular formula C7H10N2O and molecular weight 138.17 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a hydroxyl group, an ether linkage, an aromatic ring system, 2-Ethoxy-3-Methylpyrazine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 138.17 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).

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 2-Ethoxy-3-Methylpyrazine 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.
