Chemical Structure
Description
The occurrence of 5-Chloro-3,5-di-O-acetyl-2-deoxyuridine is closely related to a carbohydrate-derived structure, an amide group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5-Chloro-3,5-di-O-acetyl-2-deoxyuridine (CAS 6046-63-5), a certified reference material (molecular formula C11H11ClN2O9, MW 350.67 g/mol) for analytical method development and quality control.
The molecular framework of 5-Chloro-3,5-di-O-acetyl-2-deoxyuridine (C11H11ClN2O9) is characterized by a carbohydrate-derived structure, an amide group, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 5-Chloro-3,5-di-O-acetyl-2-deoxyuridine 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.
