Fluorescein Impurity 15 CAS 869811-23-4

Description

Compared with other compounds in its class, the molecular weight of 314.44 g/mol gives Fluorescein Impurity 15 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Fluorescein Impurity 15 (CAS 869811-23-4), a pharmacopoeial impurity reference standard (molecular formula C14H12F2S3, MW 314.44 g/mol) used for the identification and quantification of trace impurities in APIs.

Fluorescein Impurity 15 (C14H12F2S3) contains sulfur-containing functionality, fluorine substitution, a polycyclic aromatic system. 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 Fluorescein Impurity 15 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.
