Core Product Properties

1. Stable Stereopure Configuration

Strict single R-chiral structure effectively avoids racemization during heating and reaction, ensuring stable optical purity for synthetic products.

2. Dual Active Functional Groups

Equipped with hydroxyl and chloro groups, supporting multi-step derivatization and flexible molecular structure modification.

3. Excellent Solubility Performance

Well miscible with common polar organic solvents, forming homogeneous solution for continuous synthetic operations.

4. Moderate Thermal Stability

Keeps complete molecular structure under routine reaction temperature; no structural inversion below 120℃ for safe processing.

5. Low Impurity Content

Precise purification controls residual impurities, meeting high standard requirements for chiral synthesis experiments.

6. Uniform Batch Consistency

Stable production process guarantees identical optical performance and composition across different batches.

7. Mild Chemical Activity

Controllable reaction activity prevents excessive side reactions, improving target product yield.

8. Long-term Storage Stability

Retains stable stereochemical properties under sealed and dry preservation with slow quality attenuation.

Application Scope

Key chiral building block for asymmetric organic synthesis
Essential intermediate for chiral aliphatic compound derivation
Structural precursor for fine chemical customized synthesis
Stereochemical raw material for laboratory organic research

Storage & Handling Guidance

Store in airtight containers within dry and shady environments. Keep away from high temperature and humid atmosphere. Reduce frequent opening to maintain stable optical activity and avoid impurity generation.
