Chemical Structure

Praseodymium(III) iodide CAS 13813-23-5 chemical structure

Description

The occurrence of Praseodymium(III) iodide is closely related to iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Praseodymium(III) iodide (CAS 13813-23-5), molecular formula I3Pr and molecular weight 521.62 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to iodine substitution, Praseodymium(III) iodide is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 521.62 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

CATO manufactures Praseodymium(III) iodide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
