6089-09-4 - Introduction
pent-4-ynoic acid, also known as pent-4-ynoic acid, chemical formula C5H6O2. The following is an introduction to the nature, use, formulation and safety information of pent-4-ynoic acid:
Nature:
- pent-4-ynoic acid is a colorless liquid with a pungent odor.
-Its relative molecular mass is 102.1g/mol.
Use:
- pent-4-ynoic acid is an important intermediate in chemical synthesis and is used to prepare other compounds.
-It can be used for carbonylation reaction, condensation reaction and esterification reaction in organic synthesis reaction.
- pent-4-ynoic acid can also be used in the preparation of drugs, fragrances and dyes.
Preparation Method:
-The preparation of pent-4-ynoic acid can be achieved by 1-chloropentyne and acid hydrolysis. First, 1-chloropentyne is reacted with water to give the corresponding aldehyde or ketone, and then the aldehyde or ketone is converted to pent-4-ynoic acid by oxidation reaction.
Safety Information:
- pent-4-ynoic acid is an irritating chemical that can cause irritation and inflammation in contact with the skin and eyes.
-Wear protective gloves, glasses, and laboratory clothing when using pent-4-ynoic acid.
-In case of contact with skin or eyes, rinse immediately with plenty of water and seek medical attention.
