Chemical Structure
Description
CATO supplies 4-Aminopyrimidine-5-carboxylic Acid (CAS 20737-41-1), a certified reference material (molecular formula C5H5N3O2, MW 139.11 g/mol) for analytical method development and quality control.
Based on its molecular formula C5H5N3O2, 4-Aminopyrimidine-5-carboxylic Acid contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 139.11 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 4-Aminopyrimidine-5-carboxylic 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.
