Product Overview
Sodium Triacetoxyborohydride (CAS 56553-60-7), commonly known as STAB, is a mild, selective organic reducing agent. It is a white crystalline powder with high hygroscopicity, widely used in pharmaceutical, fine chemical and organic synthesis industries for reductive amination and selective reduction reactions. Produced under strict quality control, it features high purity, stable performance and good solubility in common organic solvents. For industrial synthesis and scientific research use only.
Product Features
- High Purity: ≥95.0% (typical ≥97.0%), low impurities, meets industrial and research grade standards.
- Mild Reducibility: Selectively reduces iminium ions without affecting most carbonyl groups, avoiding over-reduction.
- High Safety: Non-toxic by-products, less hazardous than sodium cyanoborohydride (NaBH3CN).
- Good Solubility: Soluble in THF, DCM, chloroform and other organic solvents.
- Strict Quality Control: Each batch is tested; standard COA and MSDS available.
- Stable Quality: Consistent performance under proper storage conditions.
Physical & Chemical Properties
Physical Properties
- Appearance: White crystalline powder

Chemical Properties
- Chemical Stability: Stable at room temperature under dry conditions; decomposes when exposed to moisture, releasing acetic acid.
- Reducing Property: Mild reducing agent, selectively reduces imines, enamines and heteroaromatics.
- Incompatibility: Reacts violently with water, alcohols, strong acids and oxidants.
- Thermal Stability: Decomposes above 120 °C, releasing toxic boron-containing fumes.
Applications
- Pharmaceutical Industry: Key reagent for reductive amination in drug synthesis (e.g., amine-containing APIs).
- Fine Chemicals: Reduction of imines, enamines and heterocyclic compounds; synthesis of amine derivatives.
- Organic Synthesis: Borohydration of alkenes; alternative to toxic sodium cyanoborohydride.
- Research Laboratories: Used in organic chemistry research and synthetic method development.
Usage Restriction: For industrial synthesis and scientific research only. Strictly forbidden for illegal use.
Storage & Transportation Instructions
Storage Conditions
Store in a cool, dry, dark and well-ventilated warehouse. Keep containers tightly sealed under nitrogen/argon atmosphere. Store separately from water, alcohols, strong acids and oxidants. Recommended storage temperature: 10–25 °C. Reseal immediately after opening.
