Description

Otophylloside B 4'''-o-β-D-Cymaropyranoside is a specialized steroidal glycoside compound derived from natural sources. This high-purity reference standard is critical for analytical research, method development, and quality control in the pharmaceutical and phytochemical industries. It is primarily sought by research institutions, analytical laboratories, and manufacturers engaged in the development and standardization of herbal medicines and bioactive natural products.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for the identification, assay, and impurity profiling of related herbal extracts and formulations.
• Bioactivity Research: Serves as a key compound in pharmacological studies investigating potential therapeutic effects, including anti-inflammatory, anti-tumor, or cardiovascular activities.
• Analytical Method Development: Essential for developing and validating precise HPLC, LC-MS, or UPLC methods for the quantification of steroidal glycosides in complex matrices.
• Quality Control (QC) & Assurance: Employed in the in-house QC testing of raw botanical materials and finished products to ensure batch-to-batch consistency and regulatory compliance.
• Natural Product Isolation & Synthesis: Acts as a target molecule for isolation protocols or as a precursor/intermediate in semi-synthetic studies for novel drug candidates.

Quality Control

Every batch of Otophylloside B 4'''-o-β-D-Cymaropyranoside is produced and analyzed under strict quality management protocols. Our products undergo rigorous identity confirmation, purity analysis, and stability testing to ensure they meet the exacting standards required for research and development. A comprehensive Certificate of Analysis (COA) detailing purity, analytical methods (e.g., HPLC, NMR), and results is provided with each shipment to guarantee traceability and compliance.

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) and should be handled in a low-humidity environment. For long-term storage, consider desiccant use and inert atmosphere to maintain stability.
