Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4,4-Dibromo-2,6-di-tert-butylcyclohexa-2,5-dienone.
4,4-Dibromo-2,6-di-tert-butylcyclohexa-2,5-dienone (CAS 1144-36-1), molecular formula C14H20Br2O and molecular weight 364.12 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4,4-Dibromo-2,6-di-tert-butylcyclohexa-2,5-dienone (C14H20Br2O) is characterized by a hydroxyl group, an ether linkage, 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. 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 4,4-Dibromo-2,6-di-tert-butylcyclohexa-2,5-dienone 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.
