As a certified reference material (CRM), Methyl 2-((1,3-dimethyl-2,6-dioxo-1,2,3,6-tetrahydropyrimidin-4-yl)thio)acetate 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.
CATO supplies Methyl 2-((1,3-dimethyl-2,6-dioxo-1,2,3,6-tetrahydropyrimidin-4-yl)thio)acetate (CAS 494763-49-4), a certified reference material (molecular formula C9H12N2O4S, MW 244.27 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Methyl 2-((1,3-dimethyl-2,6-dioxo-1,2,3,6-tetrahydropyrimidin-4-yl)thio)acetate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 244.27 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
