Chemical Structure
Description
CATO supplies Rhenium pentacarbonyl(I) bromide (CAS 14220-21-4), a certified reference material (molecular formula BrReCO, MW 294.12 g/mol) for analytical method development and quality control.
Structurally, Rhenium pentacarbonyl(I) bromide (BrReCO) contains a hydroxyl group, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.5, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 294.12 g/mol, it falls into the medium-molecular-weight range. 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 Rhenium pentacarbonyl(I) bromide 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.
