Description
CATO manufactures Goserelin EP Impurity I Acetate 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.
CATO supplies Goserelin EP Impurity I Acetate (CAS CATO-C4X-19209), a pharmacopoeial impurity reference standard (molecular formula C69H98N20O16C2H4O2, MW 1523.72 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Goserelin EP Impurity I Acetate is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1523.72 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
