Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1,9-Dibromononane (CAS 4549-33-1), molecular formula C9H18Br2 and molecular weight 286.05 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to bromine substitution, 1,9-Dibromononane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 286.05 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.
CATO manufactures 1,9-Dibromononane 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.
