Applications

This compound is a key heterocyclic intermediate in pharmaceutical and agrochemical synthesis, featuring an amino-thiophene core fused with a cyclohexane ring. It serves as a critical building block for constructing various biologically active molecules, especially in the development of anti-inflammatory, analgesic, and antimicrobial agents. Its primary amino and ester groups enable versatile derivatization via condensation, amidation, and cyclization reactions. In drug discovery, it is widely used to synthesize thiophene-based kinase inhibitors, G-protein coupled receptor (GPCR) ligands, and antifungal candidates. Additionally, it acts as a precursor for preparing organic semiconductors and dyes, leveraging its conjugated heterocyclic structure. Its high purity and stable crystalline form make it a valuable raw material for laboratory research and industrial-scale fine chemical production.

Safety Information

GHS Classification: H315 (Causes skin irritation), H319 (Causes serious eye irritation), H335 (May cause respiratory irritation)
Signal Word: Warning
Risk Codes: R36/37/38
Safety Codes: S26; S36/37; Keep away from food and feed
Acute toxicity data is limited; it is considered low-to-moderate irritant. Prolonged or repeated skin contact may cause redness, itching, or dermatitis; rinse with plenty of water for 15 minutes. Eye contact can trigger severe irritation, tearing, and conjunctivitis; flush with water for ≥15 minutes and seek medical attention if symptoms persist. Inhalation of dust may irritate the respiratory tract, causing cough or sore throat. Use in a well-ventilated fume hood; wear nitrile gloves, safety goggles, and a dust mask. Store separately from oxidants, acids, and food. Dispose of waste per local hazardous waste regulations; do not release into the environment.
