We will put two photos below so you can check their difference.

It is a semi-synthetic beta-lactam carbapenem antibiotic widely used for research.

Imipenem was first discovered and patented by Merck scientists Burton Christensen, William Leanza, and Kenneth Wildonger in the 1970s.

It was not approved for medical use in the USA until 1985.

Imipenem was found to be highly resistant to the β-lactamase enzymes produced by many multiple drug-resistant Gram-negative bacteria, so it is widely used to treat infections that can not be cured by other antibiotics.

There are many formulations on the market combining cilastatin sodium.

How To Ship and Store Imipenem API?

For shipments of small quantities, such as 100~200G, shipping by couriers such as FedEx or TNT is the most suitable way.

#1. How To Ship

As you all know, to ship chemicals out from China by air or by courier, FedEx or TNT would require a certificate of safe air transportation issued by DGM or other institutions.

The good thing is that DGM has tested and proved that imipenem is safe for shipping by air or courier.

It is not a dangerous chemical but regarded suitable to be shipped as common goods.

Thus, shipping it by air or courier is not a problem here in China and we will make sure you can get the package very quickly.

As it is an antibiotic, the temperature during the transportation should not exceed 35 Degrees Celsius within a shipping period of 7 days.

It is better that you can add some ice bags into the package so the product won’t go bad.

#2. How To Store

As for the long-term storage, it is recommended to be stored in a freezer under -20 Degrees Celsius, protected from light and moisture.

It is preferred to be vacuum-packed so it will not be oxidized by the oxygen in the package.

For short-period storage, you have to make sure the storage temperature is around 2~8 Degrees Celsius.

The material should be used within 2~3 days so the testing results will not be affected.
