Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Thulium(III) iodide.
Thulium(III) iodide (CAS 13813-43-9) is a high-purity analytical reference standard with the molecular formula I3Tm and a molecular weight of 549.65 g/mol.
Owing to iodine substitution, Thulium(III) iodide is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 549.65 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures Thulium(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.
