Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including S-Deoxo-3-Keto-17-Acetoxy Fulvestrant.
S-Deoxo-3-Keto-17-Acetoxy Fulvestrant (CAS 415927-29-6), molecular formula C34H51F5O3S and molecular weight 634.82 g/mol, is a CATO reference standard with documented purity and traceability.
S-Deoxo-3-Keto-17-Acetoxy Fulvestrant (C34H51F5O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.
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 S-Deoxo-3-Keto-17-Acetoxy Fulvestrant 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.
