Chemical Structure
Description
The occurrence of Thymidylyl-3-5-thymidine ammonium salt is closely related to a flavonoid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Thymidylyl-3-5-thymidine ammonium salt (CAS 1969-54-6) is a high-purity analytical reference standard with the molecular formula C20H27N4O12PH3N and a molecular weight of 563.46 g/mol.
Thymidylyl-3-5-thymidine ammonium salt (C20H27N4O12PH3N) contains a flavonoid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), Thymidylyl-3-5-thymidine ammonium 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.
