Description

Carbamic Acid, (2-Methyl-3-Thienyl)-, 1,1-Dimethylethyl Ester (9Ci) is a specialized organic compound featuring a thiophene core, a carbamate ester group, and a tert-butyl protecting moiety. This unique molecular architecture makes it a valuable building block in advanced organic synthesis, particularly for the development of novel active pharmaceutical ingredients (APIs) and agrochemicals. It is primarily sought after by research and development chemists in the pharmaceutical, agrochemical, and fine chemical industries for constructing complex heterocyclic molecules.

Application

• Pharmaceutical Intermediate: A key synthon in the research and development of new drug candidates, particularly those targeting central nervous system (CNS) disorders or possessing specific receptor activity.
• Agrochemical Synthesis: Used as a precursor in the creation of novel herbicides, fungicides, or insecticides, leveraging the bioactivity of the thiophene ring.
• Fine Chemical Production: Serves as a versatile building block for synthesizing complex organic molecules used in materials science, dyes, or specialty polymers.
• Academic & Contract Research: Employed in university and CRO laboratories for methodological studies in heterocyclic and medicinal chemistry.
• Custom Synthesis Projects: A starting material for bespoke chemical synthesis, where the tert-butyl carbamate (Boc) group acts as a protective group for amines.

Quality Control

Our Carbamic Acid, (2-Methyl-3-Thienyl)-, 1,1-Dimethylethyl Ester is produced under strict quality management protocols. Every batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, the container should be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Recommended long-term storage temperature is 2-8°C.
