Chemical Structure
Description
Olopatadine Ethyl Ester (HCl) (CAS 113806-03-4), molecular formula C23H27NO3 and molecular weight 365.47 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C23H27NO3, Olopatadine Ethyl Ester (HCl) contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 365.47 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Olopatadine Ethyl Ester (HCl) 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.
