Description

5-Methyl-1H-Indole-7-Carboxylic Acid is a high-purity, functionalized indole derivative serving as a critical building block in advanced organic synthesis. Its value lies in providing a versatile scaffold for constructing complex molecules, particularly in the development of novel active pharmaceutical ingredients (APIs) and agrochemicals. This compound is essential for research chemists and process development scientists in the pharmaceutical, agrochemical, and fine chemical industries seeking to introduce specific indole-based structural motifs into their target molecules.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of novel drug candidates, particularly those targeting neurological and oncological pathways where the indole core is prevalent.
• Agrochemical Synthesis: Used in the research and development of new herbicides, fungicides, and plant growth regulators that utilize indole chemistry.
• Material Science Research: Serves as a monomer or functionalizing agent in the development of specialty polymers and organic electronic materials.
• Bioconjugation & Probe Development: The carboxylic acid group enables coupling reactions for creating fluorescent probes, biochemical tags, and antibody-drug conjugates (ADCs).
• Academic & Contract Research: A valuable reagent for methodological studies in organic chemistry and for contract research organizations (CROs) performing custom synthesis.

Quality Control

Our 5-Methyl-1H-Indole-7-Carboxylic Acid is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC, NMR, and mass spectrometry, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical quality attributes are provided and available upon request, supporting your regulatory and R&D documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which may affect stability and handling properties.
