Chemical Structure
Description
The occurrence of Strontium iodide hexahydrate is closely related to iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Strontium iodide hexahydrate (CAS 7790-40-1), a certified reference material (molecular formula ISrH2O, MW 232.54 g/mol) for analytical method development and quality control.
Strontium iodide hexahydrate (ISrH2O) contains 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.
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 Strontium iodide hexahydrate 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.
