Chemical Structure
Description
As a certified reference material (CRM), 3-Amino-3-(pyrazin-2-yl)butanoic acid 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.
3-Amino-3-(pyrazin-2-yl)butanoic acid (CAS 1270477-92-3), molecular formula C8H11N3O2 and molecular weight 181.19 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Amino-3-(pyrazin-2-yl)butanoic acid (C8H11N3O2) 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.
