Description

Phenylalanine Betaine is a high-purity, zwitterionic compound derived from the amino acid L-phenylalanine and the natural osmolyte glycine betaine. This specialized ingredient is valued for its unique biochemical properties, serving as a potent osmoprotectant and stabilizer in advanced formulations. It is essential for manufacturers in the pharmaceutical, cosmetic, and high-end nutraceutical industries seeking to enhance product stability and cellular protection. Our supply of Phenylalanine Betaine CAS NO 56755-22-7 is characterized by stringent quality control and reliable global logistics.

Application

Phenylalanine Betaine is utilized in sophisticated applications where stability and biological activity are paramount.

• Pharmaceutical Formulations: As an active pharmaceutical ingredient (API) intermediate or excipient in injectables and ophthalmics for its osmoprotective and cell membrane-stabilizing effects.
• Cosmetic & Skincare Products: A key active in anti-aging serums, moisturizers, and eye creams to protect skin cells from osmotic stress and improve skin barrier function.
• Advanced Nutraceuticals: Incorporated into dietary supplements targeting cognitive health and cellular longevity due to its structural relationship to key neurotransmitters.
• Biochemical Research: Used as a standard or reagent in studies of osmolyte pathways, protein stabilization, and neurodegenerative disease models.
• Cell Culture Media: An additive to protect sensitive cell lines (e.g., mammalian, bacterial) from osmotic shock during fermentation or bioprocessing.
• Diagnostic Reagents: A component in specialized diagnostic kits and buffers that require precise ionic and stabilizing properties.
