Description
CATO manufactures 2-Bromo-1-chloro-4-methyl-benzene 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.
2-Bromo-1-chloro-4-methyl-benzene (CAS 57310-39-1), molecular formula C7H6BrCl and molecular weight 205.48 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-Bromo-1-chloro-4-methyl-benzene (C7H6BrCl) contains chlorine/bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 205.48 g/mol, it falls into the medium-molecular-weight range. 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.
