1. 5-Phenyltetrazole is a key pharmacophore used in medicinal chemistry, notably as a bioisostere for carboxylic acids in angiotensin receptor blockers (ARBs) and other therapeutic agents.
2. 5-Phenyltetrazole serves as a versatile intermediate in organic synthesis for producing pharmaceuticals (e.g., cephalosporin antibiotics), agrochemicals, and diverse heterocyclic compounds.
3. 5-Phenyltetrazole is employed in material science as a stable photosensitive agent, a corrosion inhibitor for metals, and as a ligand in the synthesis of metal-organic frameworks (MOFs) and coordination polymers.
Packed in 1kg/bag, 25kg/drum
1. 5-Phenyltetrazole is harmful if swallowed, with an oral LD50 of 1901 mg/kg in rats, and may cause skin, eye, and respiratory tract irritation.
2. 5-Phenyltetrazole is a flammable solid (Hazard Class 4.1) and may decompose upon heating to emit toxic gases including nitrogen oxides, carbon monoxide, and carbon dioxide.
3. Wear appropriate personal protective equipment (gloves, safety goggles, protective clothing) and use respiratory protection if dust is generated. In case of eye contact, rinse immediately with plenty of water for at least 15 minutes and seek medical attention.
1. Isolate the spill area and remove all sources of ignition. Ensure adequate ventilation and wear appropriate personal protective equipment.
2. Use spark-proof tools to carefully sweep or vacuum the spilled material and place it into a suitable, sealed container for disposal.
3. Prevent the material from entering drains or waterways, and dispose of the collected waste in accordance with local environmental regulations.
1. Store 5-Phenyltetrazole in a tightly closed container in a cool, dry, well-ventilated place, away from heat, sparks, and open flames, as it is a flammable solid.
2. Keep 5-Phenyltetrazole separate from strong oxidizing agents, strong acids, acid anhydrides, and acid chlorides.
3. 5-Phenyltetrazole poses a risk of explosion if heated under confinement; handle with non-sparking tools and use explosion-proof equipment.
