Leuprorelin EP impurity E TFA CAS 1926163-23-6

Description

Compared with other compounds in its class, the molecular weight of 1323.44 g/mol gives Leuprorelin EP impurity E TFA distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Leuprorelin EP impurity E TFA (CAS 1926163-23-6), a pharmacopoeial impurity reference standard (molecular formula C59H84N16O12C2HF3O2, MW 1323.44 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C59H84N16O12C2HF3O2, Leuprorelin EP impurity E TFA contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 1323.44 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 Leuprorelin EP impurity E TFA 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.
