Applications of 3844-53-9
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Used as a lysine modification moiety in the synthesis of peptide-based drugs, antimicrobial peptides, and targeted drug delivery systems | Applied as a protected form of L-lysine in solid-phase peptide synthesis (SPPS); the ethyl ester group masks the carboxyl group, while the dihydrochloride salt enhances water solubility and stability; subsequent deprotection is carried out under basic conditions |
| Food Additives | Used as a nutritional fortificant to supplement dietary lysine, particularly in low-protein foods and foods for special medical purposes | Added during late-stage food processing (e.g., prior to spray drying); pH and temperature must be controlled to prevent racemization; compliant with GB 14880-2012 and FDA GRAS requirements |
| Cosmetics | Functions as a humectant and keratin conditioner to enhance skin permeability and support active ingredient delivery | Incorporated into aqueous phases of emulsions and serums at typical concentrations of 0.1–2.0%; remains stable within a pH range of 4.5–6.5 |
| Biological Reagents | Used to adjust amino acid composition in cell culture media to support high-density mammalian cell culture (e.g., CHO cells) | Dissolved in sterile water at specified molar ratios, sterilized by filtration, and added to basal media (e.g., DMEM/F12) to partially replace free L-lysine, thereby improving cell adhesion and proliferation |
