Chemical Structure
Description
The occurrence of 5-Bromovaleryl chloride 5-bromovaleroyl chloride 5-bromovaleric chloride 5-bromo-pentanoyl chloride 5-bromopentanoyl chloride 5-Bromovaleric acid chloride 4509-90-4 is closely related to a hydroxyl group, an ether linkage, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Bromovaleryl chloride 5-bromovaleroyl chloride 5-bromovaleric chloride 5-bromo-pentanoyl chloride 5-bromopentanoyl chloride 5-Bromovaleric acid chloride 4509-90-4 (CAS 4509-90-4), molecular formula C5H8BrClO and molecular weight 199.47 g/mol, is a CATO reference standard with documented purity and traceability.
5-Bromovaleryl chloride 5-bromovaleroyl chloride 5-bromovaleric chloride 5-bromo-pentanoyl chloride 5-bromopentanoyl chloride 5-Bromovaleric acid chloride 4509-90-4 (C5H8BrClO) contains a hydroxyl group, an ether linkage, chlorine/bromine 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
