Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
Valganciclovir Impurity 1 (S, S-Isovalganciclovir Impurity) (CAS 1401562-13-7) is a high-purity analytical reference standard with the molecular formula C14H22N6O5HCl and a molecular weight of 390.82 g/mol.
Valganciclovir Impurity 1 (S, S-Isovalganciclovir Impurity) (C14H22N6O5HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
CATO manufactures Valganciclovir Impurity 1 (S, S-Isovalganciclovir Impurity) 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.
