The occurrence of Proguanil EP Impurity D Hydrochloride is closely related to chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Proguanil EP Impurity D Hydrochloride (CAS 35708-82-8) is a certified pharmaceutical impurity reference standard with the molecular formula C8H19N5HCl and a molecular weight of 221.73 g/mol.
Based on its molecular formula C8H19N5HCl, Proguanil EP Impurity D Hydrochloride contains chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 221.73 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 Proguanil EP Impurity D Hydrochloride 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.
