Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Bromo-7-methoxycyclohepta-2,4,6-trien-1-one (CAS 1728-86-5) is a high-purity analytical reference standard with the molecular formula C8H7BrO2 and a molecular weight of 215.04 g/mol.
The molecular framework of 2-Bromo-7-methoxycyclohepta-2,4,6-trien-1-one (C8H7BrO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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).
CATO manufactures 2-Bromo-7-methoxycyclohepta-2,4,6-trien-1-one 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.
