Description

Methyl 2-(4’-Acetoxy-2-Fluoro-Biphenyl-4-Yl)-Propionate-D3 is a deuterated isotopologue of a key pharmaceutical intermediate, where specific hydrogen atoms are replaced with deuterium, a stable isotope, to modify metabolic pathways and enhance drug stability. This deuteration is strategically employed to improve the pharmacokinetic and pharmacodynamic profiles of active pharmaceutical ingredients (APIs) in drug development. It is a critical building block for researchers and manufacturers in the pharmaceutical and contract research organization (CRO) sectors, particularly for developing deuterated drug candidates with extended half-lives and reduced side-effect profiles.

Application

• Deuterated Active Pharmaceutical Ingredient (API) Synthesis: Serves as a key labeled precursor in the multi-step synthesis of deuterium-enriched drug substances.
• Metabolic Stability Studies: Used in preclinical research to investigate the impact of deuteration on the metabolic rate and pathways of lead compounds.
• Pharmacokinetic (PK) and Pharmacodynamic (PD) Profiling: Essential for creating deuterated analogs to study and improve drug absorption, distribution, metabolism, and excretion (ADME) properties.
• Isotope-Labeled Internal Standards: Employed in analytical chemistry, particularly in LC-MS/MS, as a high-purity internal standard for the accurate quantification of non-deuterated analogs in biological matrices.
• Drug Discovery & Development: A valuable tool for medicinal chemists exploring the deuterium switch strategy to create new chemical entities (NCEs) with enhanced therapeutic efficacy.
• Patent Lifecycle Management: Used in the development of deuterated versions of existing blockbuster drugs to create novel, patent-protected formulations.

Quality Control

Every batch of our deuterated intermediates is produced and analyzed under strict quality management systems. We provide comprehensive Certificates of Analysis (COA) detailing isotopic purity (D-enrichment), chemical purity, and identity confirmation via advanced spectroscopic and chromatographic methods. Our quality protocols are designed to meet the stringent requirements of pharmaceutical R&D and GMP-guided production environments.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider using desiccants.
