| Application: | Acetyl chloride can be used as: • A degradation agent in the degradation of polyoxyethylene glycol monoalkyl ethers to determine the degree of ethoxylation using chromatography-mass spectrometry (MS). • A reagent with alcohols for the esterification of carboxylic acids, N-boc deprotection, and phosphoramide solvolysis reactions. |
| General description: | Acetyl chloride (acyl chloride) is an acetylation reagent used in esterification and Friedel-Crafts acylation reactions. |
