Physical and Chemical Properties |
|
Use | Tevaloyl chloride is a very important acylating reagent, which is mainly used as a pharmaceutical intermediate and the main raw material in the preparation of many amides and phenolic lipids; at present, it has been used in the production of drugs such as hydroxylamine benzylpenicillin, cefoxazolin and epinephrine. It is also used in large quantities for the production of pesticide intermediates, such as chlorotevaloyl chloride. |

Use | an intermediate in organic synthesis tevaloyl chloride is a very important acylating reagent, mainly used as pharmaceutical intermediates, in the preparation of many amides and phenolic lipids as the main raw material; Currently has been used in hydroxylamine benzylpenicillin and cefoperazone, the production of such drugs as bispentanoyl epinephrine. It is also used in large quantities for the production of pesticide intermediates, such as chlorotevaloyl chloride. |
