Description
CATO supplies Tamoxifen EP Impurity E HCl (Mixture of Z and E Isomers) (CAS CATO-C4X-123316), a pharmacopoeial impurity reference standard (molecular formula C26H29NOHCl, MW 407.98 g/mol) used for the identification and quantification of trace impurities in APIs.
Tamoxifen EP Impurity E HCl (Mixture of Z and E Isomers) (C26H29NOHCl) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 Tamoxifen EP Impurity E HCl (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.
