Description
CATO manufactures Tamoxifen EP Impurity E (Mixture of Z and E Isomers) 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.
Tamoxifen EP Impurity E (Mixture of Z and E Isomers) (CAS CATO-C4X-12336) is a certified pharmaceutical impurity reference standard with the molecular formula C26H29NO and a molecular weight of 371.51 g/mol.
Structurally, Tamoxifen EP Impurity E (Mixture of Z and E Isomers) (C26H29NO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 371.51 g/mol, it falls into the moderately-high-molecular-weight range. 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.
