Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5,11-Bis(phenylsulfonyl)dibenzo[a,e]cyclooctene.
5,11-Bis(phenylsulfonyl)dibenzo[a,e]cyclooctene (CAS 468751-39-5), molecular formula C28H20O4S2 and molecular weight 484.59 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 5,11-Bis(phenylsulfonyl)dibenzo[a,e]cyclooctene (C28H20O4S2) contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 19.0, corresponding to approximately 19 ring(s) or double-bond equivalent(s). With a molecular weight of 484.59 g/mol, it falls into the moderately-high-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 5,11-Bis(phenylsulfonyl)dibenzo[a,e]cyclooctene 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.
