Chemical Structure

Cobalt(II) iodide dihydrate CAS 13455-29-3 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies Cobalt(II) iodide dihydrate (CAS 13455-29-3), a certified reference material (molecular formula CoI2H2O, MW 330.75 g/mol) for analytical method development and quality control.

Based on its molecular formula CoI2H2O, Cobalt(II) iodide dihydrate contains iodine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 330.75 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

As a certified reference material (CRM), Cobalt(II) iodide dihydrate 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.
