Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2,4,5-Trichlorobiphenyl- (CAS 208263-78-9) is a high-purity analytical reference standard with the molecular formula [13C]12H7Cl3 and a molecular weight of 269.45 g/mol.
2,4,5-Trichlorobiphenyl- ([13C]12H7Cl3) contains chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 2,4,5-Trichlorobiphenyl- 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.
