Chemical Structure
Description
Owing to an amide group, a hydroxyl group, an ether linkage, an aromatic ring system, Temozolomide EP Impurity C is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 176.14 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).
Temozolomide EP Impurity C (CAS 114601-31-9) is a certified pharmaceutical impurity reference standard with the molecular formula C6H4N6O and a molecular weight of 176.14 g/mol.
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 Temozolomide EP Impurity C 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.
