DNA/RNA Drug Optical Rotation Testing Service
DNA/RNA Drug Optical Rotation Testing Service utilizes precision optical equipment such as polarimeters to measure the optical rotation angle and specific rotation of nucleic acid drug solutions to characterize their optical activity and chiral purity.
Optical rotation is a key parameter for describing molecular optical activity. For nucleic acid drugs with chiral centers and complex conformations, any abnormality in optical rotation may indicate synthesis defects, missing modifications, or potential impurities, which can affect drug stability, binding efficiency, and clinical efficacy.
By measuring optical rotation, researchers and pharmaceutical developers can not only confirm whether the product possesses the expected stereochemical characteristics but also compare consistency across different batches, monitor production stability, and obtain reliable data to support formulation optimization and regulatory submission.
