Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,1-(1,2-Ethanediyl)bis[4-(2-methylpropyl)benzene.
1,1-(1,2-Ethanediyl)bis[4-(2-methylpropyl)benzene (CAS 119809-70-0) is a high-purity analytical reference standard with the molecular formula C22H30 and a molecular weight of 294.47 g/mol.
Structurally, 1,1-(1,2-Ethanediyl)bis[4-(2-methylpropyl)benzene (C22H30) contains a polycyclic aromatic 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 294.47 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 1,1-(1,2-Ethanediyl)bis[4-(2-methylpropyl)benzene 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.
