Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 303.27 g/mol gives M1G distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
M1G (CAS 87171-83-3), molecular formula C13H13N5O4 and molecular weight 303.27 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C13H13N5O4, M1G contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 303.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), M1G 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.
