Description

L-Alanine, 2-Hydroxyethyl Ester (9Ci) CAS NO 92303-22-5 is a versatile amino acid ester derivative, serving as a crucial chiral building block and intermediate in advanced organic synthesis. Its bifunctional structure, featuring both a protected amino acid moiety and a reactive hydroxyl group, enables its use in the creation of complex molecules with high stereochemical purity. This compound is particularly valuable for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries who require high-purity intermediates for peptide mimetics, prodrug development, and polymer synthesis.

Application

• Pharmaceutical Intermediate: Key chiral synthon for the synthesis of active pharmaceutical ingredients (APIs), prodrugs, and peptide analogs.
• Bioconjugation & Linker Chemistry: Used in the development of antibody-drug conjugates (ADCs) and other bioconjugates due to its reactive ester and hydroxyl groups.
• Polymer Science: Monomer or co-monomer for synthesizing functionalized, biodegradable polymers and hydrogels with tailored properties.
• Agrochemical Synthesis: Intermediate in the production of chiral herbicides, fungicides, and plant growth regulators.
• Cosmetic & Personal Care Ingredients: Building block for synthesizing mild, skin-compatible surfactants and conditioning agents.
• Research & Development: Essential reagent in medicinal chemistry and chemical biology for structure-activity relationship (SAR) studies.

Quality Control

Our L-Alanine, 2-Hydroxyethyl Ester is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity verification by HPLC, to ensure it meets the high standards required for research and industrial synthesis. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting identity, purity, and impurity profiles.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); therefore, containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which may affect stability and performance.
