Description

Synephrine Tartrate is a high-purity, standardized alkaloid salt derived from natural or synthetic sources. This compound is valued for its consistent potency and stability, making it a critical ingredient in formulations requiring precise bioactivity. It is primarily sought by manufacturers in the dietary supplement, pharmaceutical, and nutraceutical industries for its targeted applications.

Application

• Dietary Supplements: A key active ingredient in weight management and energy-boosting formulations, often marketed for its thermogenic properties.
• Pharmaceutical Intermediates: Serves as a chiral building block or precursor in the synthesis of more complex adrenergic agents.
• Sports Nutrition: Incorporated into pre-workout and performance blends for its stimulant-like effects.
• Research & Development: Used as a reference standard in analytical laboratories for method development and quality control of related products.
• Traditional Medicine Extracts: A standardized component in extracts of *Citrus aurantium* (bitter orange) for consistent potency.

Quality Control

Our Synephrine Tartrate is produced under strict quality management systems. Each batch is tested to ensure it meets high-purity standards suitable for dietary supplement and research applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture.
