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 [(E)-(1,2-Dihydro-2-oxo-3H-indol-3-ylidene)methyl]ferrocene.
[(E)-(1,2-Dihydro-2-oxo-3H-indol-3-ylidene)methyl]ferrocene (CAS 884338-18-5), molecular formula C14H10NOC5H5Fe and molecular weight 329.18 g/mol, is a CATO reference standard with documented purity and traceability.
[(E)-(1,2-Dihydro-2-oxo-3H-indol-3-ylidene)methyl]ferrocene (C14H10NOC5H5Fe) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 [(E)-(1,2-Dihydro-2-oxo-3H-indol-3-ylidene)methyl]ferrocene 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.
