Chemical Structure
Description
The occurrence of 5-Methylpyrazine-2-carboxamidine is closely related to a nitrile group, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Methylpyrazine-2-carboxamidine (CAS 725234-33-3), molecular formula C6H8N4 and molecular weight 136.15 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, an aromatic ring system, 5-Methylpyrazine-2-carboxamidine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 136.15 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.
As a certified reference material (CRM), 5-Methylpyrazine-2-carboxamidine 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.
