Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,4-Dibromo-2-chloro-5-methylbenzene.
1,4-Dibromo-2-chloro-5-methylbenzene (CAS 28667-41-6) is a high-purity analytical reference standard with the molecular formula C7H5Br2Cl and a molecular weight of 284.38 g/mol.
1,4-Dibromo-2-chloro-5-methylbenzene (C7H5Br2Cl) contains chlorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 1,4-Dibromo-2-chloro-5-methylbenzene 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.
