Description

9-cis-Retinyl Stearate is a high-purity, synthetic ester derivative of vitamin A, specifically the 9-cis isomer of retinol esterified with stearic acid. This compound is valued for its role as a stable, bioavailable precursor in advanced formulations requiring precise retinoid activity. It is primarily sought by manufacturers in the pharmaceutical, nutraceutical, and high-end cosmetic industries for research and product development.

Application

• Pharmaceutical Intermediates: Serves as a key synthetic intermediate or active pharmaceutical ingredient (API) in the development of retinoid-based therapies.
• Nutraceutical Formulations: Used in the production of specialized dietary supplements targeting vitamin A metabolism and cellular health.
• Advanced Cosmetic Actives: Incorporated into anti-aging and skin-rejuvenation serums and creams for its potential retinoid-like effects on skin cells.
• Biochemical Research: Employed as a reference standard or reagent in studies of retinoid biology, isomerization, and receptor binding.
• Specialty Chemical Synthesis: Acts as a building block for the synthesis of more complex retinoid analogs and derivatives.

Quality Control

Our 9-cis-Retinyl Stearate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and isomer specificity, to ensure it meets rigorous standards suitable for research and formulation. Certificates of Analysis (COA) with detailed chromatographic data are provided to guarantee batch-to-batch consistency and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C (refrigerated) or as specified on the label. This material is strictly light-sensitive and easily oxidized; prolonged exposure to air, light, or elevated temperatures should be avoided to maintain stability and potency.
