Description
As a certified reference material (CRM), 2′-Bromo-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.
2′-Bromo-2′-deoxyuridine (CAS 4753-02-0) is a high-purity analytical reference standard with the molecular formula C9H11BrN2O5 and a molecular weight of 307.10 g/mol.
Structurally, 2′-Bromo-2′-deoxyuridine (C9H11BrN2O5) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 307.10 g/mol, it falls into the moderately-high-molecular-weight range. 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.
