Description

Forsythoside H is a bioactive phenylethanoid glycoside compound isolated from plants of the *Forsythia* genus. This high-purity reference standard is critical for research and development in the pharmaceutical and nutraceutical sectors, where precise chemical identity and activity are paramount. It is primarily utilized by scientists and quality control professionals in analytical laboratories for method development, validation, and as a quantitative standard.

Application

• Pharmaceutical Reference Standard: Serves as a certified primary standard for the identification, assay, and impurity profiling of herbal extracts and finished products in pharmacopoeial testing.
• Bioactivity Research: Used in *in vitro* and *in vivo* studies to investigate its pharmacological properties, such as anti-inflammatory, antioxidant, and antiviral activities.
• Natural Product Isolation & Analysis: Essential for the qualitative and quantitative analysis of *Forsythia suspensa* and related botanical extracts in quality control laboratories.
• Nutraceutical Standardization: Employed to standardize and guarantee the potency and consistency of dietary supplements containing Forsythia extract.
• Method Development & Validation: A key component in developing and validating robust analytical methods, particularly High-Performance Liquid Chromatography (HPLC) and Liquid Chromatography-Mass Spectrometry (LC-MS) protocols.

Quality Control

Our Forsythoside H is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing including HPLC for purity, IR and MS for structural confirmation, and residual solvent analysis. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting the assay purity and confirming identity against an authenticated reference standard.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); the container must be kept tightly sealed in a dry environment to prevent degradation.
