CD Formulation has an impurity profiling database, a core technical team, and a technical platform for nucleic acid drugs analysis. The company is dedicated to offering objective, professional, and efficient laboratory R&D and analytical technical support for global pharmaceutical companies. Our services cover trace metals, extracts and leachates, residual solvents, etc., providing high-quality, high-efficiency, and comprehensive solutions.
Nucleic acid drugs are typically synthesized through solid-phase synthesis. Due to the intricate nature of their molecular structure, various impurities are easily formed during production. Detecting, identifying, quantifying, and controlling impurities in nucleic acid drugs are crucial steps to enhance the purity, safety, and quality control of the drug substance or final product. Impurities in nucleic acid drugs can originate from different sources, such as starting materials and their contaminants, reagents, solvents, leachables, and degradation products. The impurities may be organic (both resulting from the process and from the drug itself), inorganic, or elemental. The presence of these impurities is often in very small amounts or in trace amounts in highly complex sample matrices, therefore precise analytical methods are needed to determine their levels. This data is necessary for conducting the associated risk assessment or meeting submission requirements.

CD Formulation's laboratories offer pharmaceutical impurity testing for nucleic acid drug formulations, supporting your product development from early stages and throughout the drug product lifecycle. Our scientists specialize in method development and validation of appropriate analytical procedures, providing expertise in addressing extractables and leachables, detecting elemental impurities, analyzing residual solvents, and identifying process-related impurities.
Our experience encompasses all nucleic acid drug formulations, product classes, and drug delivery technologies. The insights we gain from reliable analytical studies can support your corrective and preventive action programs, accelerate your drug development programs, and streamline manufacturing impurity monitoring.
Our available services include:
Trace metals analysis in nucleic acid drugs is vital for ensuring drug safety and efficacy. Trace metals can catalyze degradation of nucleic acids, affecting stability and potency. Identifying and quantifying these metals helps in optimizing the formulation and manufacturing processes to minimize potential adverse effects.
We offer expert analysis and identification of residual solvents in pharmaceutical products to assist our clients in verifying that residual solvents have been minimized to acceptable levels, ensuring that final products comply with the limits outlined in ICH Q3C(R5) or USP <467>/ Ph. Eur. 5.4, or limits established by the pharmaceutical manufacturer for specific solvents.
Our experts have more than years of experience in specialized analysis and toxicological evaluation of extractables and leachables. Our knowledge of packaging materials enables us to identify components from even the most complex polymer formulations.
With scientists specializing in method development and validation of appropriate analytical procedures, we can overcome the challenges of low detection levels and complex impurities. Using a range of techniques, we can apply orthogonal methods to ensure robust, specific, and sensitive analysis. Our comprehensive range of characterization techniques includes:

Results:
Nucleic acids are receiving increased attention in meeting unmet medical needs. New analytical challenges have been posed in the discovery, characterization, quality control and bioanalysis of therapeutic nucleic acids. Capillary electrophoresis (CE) has proven to be an efficient separation technique and is widely used to analyze oligonucleotides and nucleic acids. This review discusses recent technological advances in capillary electrophoresis for nucleic acid analysis, such as polymer matrices, separation conditions and detection methods, and the application of capillary electrophoresis to a variety of therapeutic nucleic acids including antisense oligonucleotides (ASOs), small interfering ribonucleic acids (siRNAs), messenger ribonucleic acids (mRNAs), gene editing tools (e.g., clustering rule-based interspaced short palindromic repeats (CRISPR) based gene and cell therapies) and other nucleic acid related therapies.
