The occurrence of Zinc bromide dihydrate is closely related to a salt form, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Zinc bromide dihydrate (CAS 18921-13-6), a certified reference material (molecular formula Br2ZnH2O, MW 243.20 g/mol) for analytical method development and quality control.
Based on its molecular formula Br2ZnH2O, Zinc bromide dihydrate contains a salt form, bromine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 243.20 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Zinc bromide 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.
