What is N-Bromosuccinimide CAS 128-08-5?
N-bromosuccinimide (CAS 128-08-5) is an irreplaceable bromination/oxidation reagent in organic synthesis. Its core characteristics include:
High selectivity: Precise bromination of weak C-H bonds, suitable for the synthesis of drugs and pesticides;
Versatility: It has the functions of oxidation, preservation and material modification.
High-risk operations: Strong corrosiveness and explosion risks require strict protection.
The market classification is clear: High-purity reagents for scientific research are expensive, while industrial-grade reagents can be customized in bulk
N-Bromosuccinimide CAS 128-08-5 Use
Key reagents for organic synthesis
Bromination reaction
Selective allyl bromide/benzyl hydrogen (Wohl-Ziegler reaction)
Synthesize pharmaceutical intermediates (such as antibiotics, vitamin D₃) and pesticides (thiabendazole).
Oxidation reaction
Alcohol → aldehyde/ketone, aldehyde → carboxylic acid;
Silicon-based ethers are aldehydes in the presence of AIBN.
Industrial and functional materials
Preservation and anti-corrosion: Fruit preservatives, mold inhibitors;
Polymer additives: Rubber processing, flame-retardant polymer synthesis;
Biochemical analysis: Tryptophan modification, ascorbic acid determination.
N-Bromosuccinimide CAS 128-08-5 safety
Health risk
Irritation: Strongly corrosive to skin, eyes and mucous membranes. Contact can cause burns (R34/R35).
Toxicity: The LD₅₀ in the abdominal cavity of mice was 153 mg/kg (highly toxic); Long-term exposure can cause dermatitis or respiratory tract damage.
Protective measures: During operation, a gas mask, corrosion-resistant gloves, goggles and protective clothing must be worn.
Environmental and operational risks
Highly toxic to aquatic organisms (R50), strictly prohibited from being discharged into water bodies.
Explosion risk: Contact with aniline, hydrazine hydrate and peroxides may cause explosion. It should be stored separately
