Description

D-Biotinol is a high-purity, biologically active form of biotin, a vital water-soluble B-complex vitamin essential for numerous metabolic processes. Its primary value lies in its role as a critical raw material for the synthesis of active pharmaceutical ingredients (APIs) and advanced nutritional supplements, where consistent quality and purity are paramount. This compound is essential for manufacturers in the pharmaceutical, nutraceutical, and high-end cosmetic industries seeking a reliable source for formulations requiring precise vitamin B7 activity.

Application

• Pharmaceutical Intermediates: A key building block in the synthesis of active pharmaceutical ingredients (APIs) for medications targeting metabolic and dermatological conditions.
• Nutraceutical & Dietary Supplements: Used in the production of high-potency vitamin B7 (biotin) supplements, multivitamin complexes, and specialized clinical nutrition products.
• Cosmetic & Personal Care Actives: Incorporated into advanced skincare formulations, such as serums and hair growth treatments, for its purported benefits to skin, hair, and nail health.
• Biochemical Research & Diagnostics: Serves as a critical reagent and standard in enzymatic studies, metabolic pathway analysis, and in vitro diagnostic kit development.
• Animal Feed & Veterinary Nutrition: Utilized as a premium-grade vitamin additive in specialized feed for livestock, poultry, and pets to support optimal growth and coat condition.
• Cell Culture Media: An essential vitamin component in defined media formulations for the cultivation of mammalian and microbial cells in bioprocessing.

Quality Control

Our D-Biotinol is manufactured under strict quality management systems to ensure it meets the stringent requirements of the pharmaceutical and nutraceutical industries. Each batch is subjected to comprehensive analytical testing, including identity confirmation, purity assay, and impurity profiling via advanced techniques like HPLC and IR spectroscopy. We provide full traceability and Certificates of Analysis (COA) are available for every shipment, confirming compliance with relevant in-house specifications and supporting cGMP principles where required.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent degradation due to moisture absorption.
