Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Diphenyl-3,3,4,4,5,5-d.
Diphenyl-3,3,4,4,5,5-d (CAS 7291-05-6), molecular formula C12H4D6 and molecular weight 160.24 g/mol, is a CATO reference standard with documented purity and traceability.
Diphenyl-3,3,4,4,5,5-d (C12H4D6) contains deuterium isotope labeling, 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures Diphenyl-3,3,4,4,5,5-d 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.
