Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Uridine Impurity 1.
Uridine Impurity 1 (CAS 215110-22-8) is a certified pharmaceutical impurity reference standard with the molecular formula C25H30N2O6Si and a molecular weight of 482.60 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Uridine Impurity 1 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 482.60 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
CATO manufactures Uridine Impurity 1 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.
