Chemical Structure
Description
Ethyl 2-((7-methyl-4-oxo-4H-pyrido[1,2-a][1,3,5]triazin-2-yl)thio)acetate (CAS 306979-25-9), molecular formula C12H13N3O3S and molecular weight 279.31 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, Ethyl 2-((7-methyl-4-oxo-4H-pyrido[1,2-a][1,3,5]triazin-2-yl)thio)acetate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 279.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
CATO manufactures Ethyl 2-((7-methyl-4-oxo-4H-pyrido[1,2-a][1,3,5]triazin-2-yl)thio)acetate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
