Description

2-Methyl-4-Oxo-4-(3'-Chlorophenyl)Butyric Acid CAS NO 34243-96-4 is a key organic intermediate featuring a butyric acid backbone substituted with a methyl group and a 3-chlorophenyl ketone moiety. This specific molecular architecture makes it a versatile building block for synthesizing more complex pharmaceutical and agrochemical compounds. It is primarily sought by R&D chemists and process development teams in the fine chemical and active pharmaceutical ingredient (API) manufacturing sectors.

Application

• Pharmaceutical Intermediate: A crucial precursor in the synthesis of various active pharmaceutical ingredients (APIs), particularly those targeting central nervous system or inflammatory pathways.
• Agrochemical Synthesis: Serves as a building block for developing advanced herbicides, fungicides, or plant growth regulators, leveraging the chlorophenyl group for bioactivity.
• Organic Synthesis Research: Used in academic and industrial laboratories for constructing complex molecules, studying reaction mechanisms involving keto-acids, and developing novel synthetic methodologies.
• Fine Chemical Production: Employed in the manufacture of specialty chemicals, dyes, pigments, and functional materials where its specific chlorinated aromatic structure is required.

Quality Control

We maintain stringent quality control protocols for our chemical intermediates. Production follows cGMP guidelines where applicable, and every batch is analyzed using advanced techniques like HPLC, GC, and NMR to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to support your quality and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from strong bases, oxidizing agents, and sources of ignition. For long-term storage, consider an inert atmosphere to preserve stability.
