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 Paclitaxel Impurity N3.
Paclitaxel Impurity N3 (CAS 163594-75-0) is a certified pharmaceutical impurity reference standard with the molecular formula C20H32 and a molecular weight of 272.48 g/mol.
Based on its molecular formula C20H32, Paclitaxel Impurity N3 contains an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 272.48 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
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 Paclitaxel Impurity N3 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.
