Chemical Structure
Description
2-Methylthio-ADP Trisodium Salt (CAS 475193-31-8), molecular formula C11H14N5O10P2SNa and molecular weight 493.26 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Methylthio-ADP Trisodium Salt (C11H14N5O10P2SNa) is characterized by a carbohydrate-derived structure, an amide group, a sulfone group, a phosphate ester group. 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).
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.
As a certified reference material (CRM), 2-Methylthio-ADP Trisodium Salt 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.
