Description
As a certified reference material (CRM), 5-Methylsulfanylpyrimidine-4-carboxylic 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.
5-Methylsulfanylpyrimidine-4-carboxylic acid (CAS 69211-74-1) is a high-purity analytical reference standard with the molecular formula C6H6N2O2S and a molecular weight of 170.19 g/mol.
The molecular framework of 5-Methylsulfanylpyrimidine-4-carboxylic acid (C6H6N2O2S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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. 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.
