Description

Carbamic Acid, (3-Aminopentyl)-, 1,1-Dimethylethyl Ester (9Ci) CAS NO 210240-75-8 is a protected amine derivative, specifically a tert-butyl carbamate (Boc) of a pentylamine, serving as a crucial synthetic intermediate in advanced organic chemistry. Its primary value lies in providing a robust, orthogonal protecting group for primary amines, enabling complex multi-step synthesis in sensitive pharmaceutical and agrochemical research. This high-purity building block is essential for medicinal chemists, process R&D scientists, and fine chemical manufacturers developing novel active pharmaceutical ingredients (APIs) and other specialty organic compounds.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates, particularly in constructing peptide mimetics and complex amine-containing heterocycles.
• Peptide Chemistry: Used as a protected amino acid derivative or spacer in solid-phase and solution-phase peptide synthesis (SPPS).
• Agrochemical Synthesis: Intermediate in the production of advanced herbicides, fungicides, and insecticides that require specific amine functionalities.
• Ligand and Catalyst Development: Serves as a precursor for chiral ligands and organocatalysts used in asymmetric synthesis.
• Polymer Science: Monomer or chain extender in the synthesis of specialized polyamides, polyurethanes, or functional polymers.
• Chemical Biology & Proteomics: Tool compound for labeling, cross-linking, or modifying biomolecules in research applications.

Quality Control

Our Carbamic Acid, (3-Aminopentyl)-, 1,1-Dimethylethyl Ester is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, NMR, and mass spectrometry, to ensure high chemical purity and identity confirmation. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are provided with every shipment. We adhere to cGMP principles where applicable to support our clients in regulated pharmaceutical development.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); therefore, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from strong acids, strong bases, and oxidizing agents.
