Description
Methyl 5-(((3-methyl-3H-[1,2,3]triazolo[4,5-d]pyrimidin-7-yl)thio)methyl)furan-2-carboxylate (CAS 1058238-65-5), molecular formula C12H11N5O3S and molecular weight 305.31 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Methyl 5-(((3-methyl-3H-[1,2,3]triazolo[4,5-d]pyrimidin-7-yl)thio)methyl)furan-2-carboxylate (C12H11N5O3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), Methyl 5-(((3-methyl-3H-[1,2,3]triazolo[4,5-d]pyrimidin-7-yl)thio)methyl)furan-2-carboxylate 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.
