Chemical Structure

Ethyl 5-methoxypyrazine-2-carboxylate CAS 54013-05-7 chemical structure

Description

The occurrence of Ethyl 5-methoxypyrazine-2-carboxylate is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ethyl 5-methoxypyrazine-2-carboxylate (CAS 54013-05-7), molecular formula C8H10N2O3 and molecular weight 182.18 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Ethyl 5-methoxypyrazine-2-carboxylate (C8H10N2O3) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

As a certified reference material (CRM), Ethyl 5-methoxypyrazine-2-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
