Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 247.55 g/mol gives Phentolamine Impurity 20 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Phentolamine Impurity 20 (CAS CATO-C4X-224720), a pharmacopoeial impurity reference standard (molecular formula C6H12Cl2N4HCl, MW 247.55 g/mol) used for the identification and quantification of trace impurities in APIs.
Phentolamine Impurity 20 (C6H12Cl2N4HCl) contains chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 Phentolamine Impurity 20 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.
