Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 454.68 g/mol gives Testosterone Impurity 4 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Testosterone Impurity 4 (CAS CATO-C4X-24324) is a certified pharmaceutical impurity reference standard with the molecular formula C30H46O3 and a molecular weight of 454.68 g/mol.
The molecular framework of Testosterone Impurity 4 (C30H46O3) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
CATO manufactures Testosterone Impurity 4 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.
