This chiral Boc-protected D-serine methyl ester is core chiral amino acid intermediate for peptide synthesis and small-molecule API manufacturing, widely applied in asymmetric synthesis of β-lactam antibiotics, antiviral nucleoside drugs and targeted anticancer small-molecule medicines. Its protected amino and hydroxyl active groups enable selective peptide coupling via deprotection reaction under mild acidic condition, commonly used for solid-phase peptide synthesis of polypeptide raw material following Fmoc/Boc dual protection synthetic route. In pharmaceutical impurity standard field, high-purity grade serves as reference working standard for serine-related API impurity qualitative and quantitative HPLC testing complying with EP and USP pharmacopoeia requirements. Besides drug synthesis, it is key building block for chiral catalyst preparation in organic asymmetric catalysis research, applied for developing new enzyme inhibitor candidates targeting serine protease in biopharmaceutical lab development. Global custom synthesis factories stock this product for fine chemical outsourcing and chiral intermediate bulk supply for pharmaceutical R&D institutes.
Low acute oral toxicity for mammals, but fine crystalline dust irritates skin, ocular mucosa and respiratory tract tissues. Direct skin contact triggers erythema and itching symptom; flush contaminated skin with plenty of running clean water over 15 minutes right after exposure. Dust splashing into eyes causes conjunctival congestion and stabbing pain, maintain continuous eye rinsing no less than 15 min and seek professional medical care if irritation persists. Inhalation of powder irritates nasopharynx and trachea inducing dry cough and throat discomfort; all weighing and feeding operations must be performed in well-ventilated fume hood equipped with nitrile gloves, dust-proof safety goggles and disposable dust respirator. Store separately from food chemicals, strong acid and oxidizing agents in low-temperature shaded warehouse; production waste liquid and solid residues should be treated as general chemical waste per local environmental laws, forbidden arbitrary discharge into water body and soil.
