Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 1228.24 g/mol gives Desmopressin Tyrosine Oxidation Impurity 2 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Desmopressin Tyrosine Oxidation Impurity 2 (CAS CATO-C4X-221519), a pharmacopoeial impurity reference standard (molecular formula C46H63N15O14S2C2HF3O2, MW 1228.24 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, Desmopressin Tyrosine Oxidation Impurity 2 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1228.24 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.
CATO manufactures Desmopressin Tyrosine Oxidation Impurity 2 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.
