Chemical Structure
Description
The occurrence of (R)-2-Amino-3-((1-methyl-2,4-dioxo-1,2,3,4-tetrahydropyrimidin-5-yl)thio)propanoic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(R)-2-Amino-3-((1-methyl-2,4-dioxo-1,2,3,4-tetrahydropyrimidin-5-yl)thio)propanoic acid (CAS 67797-19-7), molecular formula C8H11N3O4S and molecular weight 245.26 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, (R)-2-Amino-3-((1-methyl-2,4-dioxo-1,2,3,4-tetrahydropyrimidin-5-yl)thio)propanoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 245.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), (R)-2-Amino-3-((1-methyl-2,4-dioxo-1,2,3,4-tetrahydropyrimidin-5-yl)thio)propanoic 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.
