For professionals in the chemical and life sciences industries, understanding the precise chemical properties and specifications of raw materials is fundamental to successful product development and manufacturing. D-Lysine hydrochloride (CAS 7274-88-6) is an essential amino acid derivative with a specific set of characteristics that dictate its utility across various applications, from pharmaceuticals to animal nutrition.

D-Lysine hydrochloride, also known by synonyms such as D-2,6-Diaminohexanoic acid monohydrochloride or H-D-Lys-OH·HCl, has the molecular formula C6H15ClN2O2. Its molecular weight is approximately 182.65 g/mol. This compound is typically presented as a white crystal or crystalline powder, which is characteristic of many amino acid salts. Its appearance is a key visual indicator of its quality and purity, which are critical for its intended uses.

The specifications for D-Lysine hydrochloride are vital for ensuring its performance. A typical assay standard requires a purity of ≥98.0%. This high level of purity is essential for applications where contaminants could negatively impact the final product, such as in pharmaceutical formulations or sensitive biochemical assays. Another important parameter is the specific rotation, which for D-Lysine hydrochloride is usually around -21º (measured under specific conditions, e.g., c=8, 6N HCl). This optical activity is a defining characteristic of the D-isomer and is crucial for applications where stereochemistry matters.

The melting point of D-Lysine hydrochloride is also an important specification, often reported as 266 °C with decomposition (dec.). This high melting point indicates a stable crystalline structure. Solubility is another key property; D-Lysine hydrochloride is typically soluble in water and dilute hydrochloric acid, which facilitates its incorporation into aqueous formulations and solutions common in many industrial processes.
