Description

4-Formyl-Benzoic Acid Mono tert-Butyl Ester is a versatile aromatic aldehyde and ester derivative, serving as a key protected intermediate in advanced organic synthesis. Its bifunctional nature, featuring both a formyl group and a protected carboxylic acid, makes it invaluable for constructing complex molecular architectures where selective reactivity is required. This compound is primarily sought after by R&D chemists and process development scientists in the pharmaceutical and agrochemical industries for applications such as API synthesis and the development of novel active ingredients.

Application

• Pharmaceutical Intermediate: A crucial building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring a protected benzoic acid moiety.
• Agrochemical Synthesis: Used in the research and production of herbicides, fungicides, and other crop protection agents.
• Ligand and Catalyst Development: Serves as a precursor for synthesizing specialized ligands used in asymmetric catalysis and metal-organic frameworks (MOFs).
• Polymer Chemistry: Employed in the creation of specialty monomers for high-performance polymers and functional materials.
• Organic Synthesis Reagent: Acts as a key starting material for multi-step syntheses, including the preparation of aldehydes, acids, and heterocyclic compounds.
• Chemical Research & Development: Essential for academic and industrial R&D projects exploring new chemical entities and reaction pathways.

Quality Control

Our 4-Formyl-Benzoic Acid Mono tert-Butyl Ester is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its sensitivity to light and potential for oxidation, prolonged exposure to air and light should be avoided. Keep the container tightly sealed when not in use.
