Description
As a certified reference material (CRM), 4'-Methyl-2,3,4,5-tetrahydro-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.
4'-Methyl-2,3,4,5-tetrahydro-1,1'-biphenyl (CAS 1821-23-4) is a high-purity analytical reference standard with the molecular formula C13H16 and a molecular weight of 172.27 g/mol.
4'-Methyl-2,3,4,5-tetrahydro-1,1'-biphenyl (C13H16) contains an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
