Quality Control

Our (S)-S-(2-Amino-2-Carboxyethyl)-D-Homocysteine is produced under strict quality management protocols to ensure high purity and batch-to-batch consistency suitable for research applications. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, chiral purity, and identification data. We adhere to relevant standards for fine chemicals, and specifications can be tailored to meet specific research-grade requirements upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption, which can affect stability and purity. For long-term storage, consider desiccants or inert atmosphere.
