Chemical Structure

3-Iodopyridine 1-oxide CAS 22447-55-8 chemical structure

Description

As a certified reference material (CRM), 3-Iodopyridine 1-oxide 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.

3-Iodopyridine 1-oxide (CAS 22447-55-8) is a high-purity analytical reference standard with the molecular formula C5H4INO and a molecular weight of 221.00 g/mol.

3-Iodopyridine 1-oxide (C5H4INO) contains an amide group, a hydroxyl group, an ether linkage, iodine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
