Chemical Structure
Description
The occurrence of 1-Bromo-4,6-nonadecadiyne is closely related to bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-Bromo-4,6-nonadecadiyne (CAS 376591-04-7) is a high-purity analytical reference standard with the molecular formula C19H31Br and a molecular weight of 339.35 g/mol.
The molecular framework of 1-Bromo-4,6-nonadecadiyne (C19H31Br) is characterized by bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 1-Bromo-4,6-nonadecadiyne 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.
