Wish list (0)Isomer Impurity Reference Standards
This category focuses on various stereoisomeric impurities present in drug molecules, encompassing enantiomers, diastereomers, and geometric isomers. Due to the significant differences in pharmacological activity, metabolic pathways, or toxicity that may be exhibited by different isomers, precise control of isomeric impurities is a core challenge in chiral drug development. We provide high optical purity isomeric reference standards, including enantiomers of single configuration and diastereomers of specific configuration, accompanied by complete spectral data (NMR, LC-MS) and optical rotation/chiral HPLC purity reports. Our products assist you in establishing highly selective chiral separation and analysis methods, evaluating the chiral selectivity of synthesis processes, and ensuring that the final product meets the strict requirements for chiral purity set by ICH Q3A and various national pharmacopoeias.
