Chemical Structure

5-Iodo-2,4-dimethoxypyrimidine CAS 52522-99-3 chemical structure

Description

The occurrence of 5-Iodo-2,4-dimethoxypyrimidine is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-Iodo-2,4-dimethoxypyrimidine (CAS 52522-99-3), molecular formula C6H7IN2O2 and molecular weight 266.04 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-Iodo-2,4-dimethoxypyrimidine (C6H7IN2O2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, 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. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
