Chemical Structure
Description
The occurrence of Tretinoin Impurity 25 is closely related to organophosphorus functionality, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Tretinoin Impurity 25 (CAS CATO-C4X-196925) is a certified pharmaceutical impurity reference standard with the molecular formula C33H38P and a molecular weight of 465.63 g/mol.
Based on its molecular formula C33H38P, Tretinoin Impurity 25 contains organophosphorus functionality, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 465.63 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 Tretinoin Impurity 25 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.
