Description

(S)-Hydratropaldehyde CAS NO 33530-47-1 is a high-purity chiral aldehyde, a key building block in asymmetric synthesis. Its value lies in its ability to introduce a specific stereocenter into target molecules, enabling the production of enantiomerically pure intermediates. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and fine chemical industries who require precise control over molecular chirality for developing active ingredients and advanced materials.

Application

• Pharmaceutical Intermediate: A critical chiral synthon for the synthesis of enantiomerically pure active pharmaceutical ingredients (APIs), particularly in cardiovascular and central nervous system (CNS) drug candidates.
• Agrochemical Synthesis: Used in the production of chiral pesticides and herbicides, where the specific stereochemistry can significantly influence biological activity and environmental safety.
• Fine Chemical Building Block: Serves as a versatile starting material for synthesizing complex fragrances, flavors, and specialty chemicals requiring defined stereochemistry.
• Asymmetric Catalysis Research: Employed as a standard substrate or ligand precursor in academic and industrial research to develop and test new asymmetric catalytic methodologies.
• Liquid Crystal & Advanced Material Precursor: Utilized in the synthesis of chiral dopants and organic compounds for liquid crystal displays (LCDs) and other optoelectronic materials.

Quality Control

Our (S)-Hydratropaldehyde is manufactured under strict quality management systems. Each batch is subjected to comprehensive analytical testing, including chiral purity analysis by HPLC, to ensure it meets the high standards required for synthetic applications. A Certificate of Analysis (COA) detailing identity, purity, enantiomeric excess, and impurity profile is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place at 2-8°C for long-term stability. This compound is easily oxidized and light-sensitive; prolonged exposure to air, moisture, or light should be avoided to maintain purity and chiral integrity.
