Application description

Morphine is an opiate which is used as pain medication. It is Schedule II controlled substance. Codeine is an opiate medication used as effective pain drug as well as a component of cough medications. Codeine is Schedule II controlled substance. Oxycodone is opioid pain medication. It is Schedule II controlled substance. Cocaine is a strong stimulant mostly used as recreational drug. It is Schedule II controlled substance. Hydrocodone is an opioid derived from codeine and one of the opioid alkaloids in opium poppy. It is a narcotic analgesic. Hydrocodone is used to treat moderate to severe pain. It is Schedule II controlled substance. Analysis of drugs of abuse and controlled substances is an important task. All 5 compounds are hydrophobic and basic in nature, thye retain on Coresep 100 column by combination of reversed-phase and cation-exchange mechanisms. Amount of ACN, buffer pH and buffer concentration can be used to adjust retention time and selectivity of this separation. The method can be used for analysis of illegal drugs and controlled substances in formulations and biofluids. The method is fully compatible with mass spectrometry. Core-shell mixed-mode columns offer combination of unique selectivity and high efficiency while using regular equipment.

2. Related Impurities

Class of compounds: Aromatic acid, Aromatic base, Controlled substance, Drug
Nature of compounds: Basic, Hydrophilic, Hydrophobic

Application description

Morphine is used to relieve moderate to severe pain. It belongs to the group of medicines called narcotic analgesics (pain medicines). Morphine acts on the central nervous system (CNS) to relieve pain. When morphine is used for a long time it can cause addiction. Morphine and related impurities were analyzed by mixed-mode chromatography on Coresep core-shell multi-mode column. Retention time is controlled by amount of ACN, buffer concentration and buffer pH. This method can be used in bioanalysis to quantify morphine in biofluids and drug formulations. Core-shell mixed-mode columns offer combination of unique selectivity and high efficiency while using regular equipment.
