Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 469.79 g/mol gives PBB No. 52 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
PBB No. 52 (CAS 59080-37-4) is a high-purity analytical reference standard with the molecular formula C12H6Br4 and a molecular weight of 469.79 g/mol.
Structurally, PBB No. 52 (C12H6Br4) contains bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 469.79 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 PBB No. 52 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.
