Fluoxetine impurity 48 CAS 1429850-43-0

Description

The occurrence of Fluoxetine impurity 48 is closely related to an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Fluoxetine impurity 48 (CAS 1429850-43-0), a pharmacopoeial impurity reference standard (molecular formula C8H20N4OHCl, MW 224.73 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Fluoxetine impurity 48 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 224.73 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 Fluoxetine impurity 48 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.
