Description

(-)-Penflutizide is a high-purity, single-enantiomer chemical compound, specifically the levorotatory form of penflutizide. This compound is valued for its precise stereochemistry, which is critical for applications in advanced pharmaceutical research and development, particularly where chiral specificity influences biological activity. It serves as a key intermediate or reference standard for researchers and manufacturers in the pharmaceutical and agrochemical sectors requiring enantiomerically pure materials.

Application

• Pharmaceutical intermediate for the synthesis of chiral active pharmaceutical ingredients (APIs).
• Reference standard for analytical method development and quality control in chiral separation techniques (e.g., HPLC, Chiral GC).
• Building block in medicinal chemistry research for structure-activity relationship (SAR) studies.
• Precursor in agrochemical research for developing enantiomerically pure crop protection agents.
• Substrate for biochemical studies investigating enzyme-substrate interactions and stereoselectivity.
• Material for academic and industrial research in asymmetric synthesis and catalysis.

Quality Control

Our (-)-Penflutizide is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chiral purity assay, enantiomeric excess (ee) determination, and identification of related substances, to ensure it meets the high standards required for research and development. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming specifications for identity, purity, and strength.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed and away from moisture and direct light exposure to maintain stability and purity.
