Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2',5'-Dichloro-2,3-difluoro-6-nitro-1,1'-biphenyl.
2',5'-Dichloro-2,3-difluoro-6-nitro-1,1'-biphenyl (CAS 1361781-85-2), molecular formula C12H5Cl2F2NO2 and molecular weight 304.08 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C12H5Cl2F2NO2, 2',5'-Dichloro-2,3-difluoro-6-nitro-1,1'-biphenyl contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 304.08 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
As a certified reference material (CRM), 2',5'-Dichloro-2,3-difluoro-6-nitro-1,1'-biphenyl meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
