Chemical Structure

Desmopressin Sulfur 0xidation Impurity CAS CATO-C4X-221517 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 1199.25 g/mol gives Desmopressin Sulfur 0xidation Impurity distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Desmopressin Sulfur 0xidation Impurity (CAS CATO-C4X-221517), a pharmacopoeial impurity reference standard (molecular formula C46H64N14O13S2C2HF3O2, MW 1199.25 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 Sulfur 0xidation Impurity is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1199.25 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
