Hey there! As a supplier of veterinary raw materials, I've faced my fair share of challenges when it comes to handling these substances, especially when they've been exposed to air. In this blog, I'm gonna share some tips on how to deal with this situation, so you can keep your products in top - notch condition.
First off, let's understand why it's a big deal when veterinary raw materials are exposed to air. Air contains oxygen, moisture, and other gases that can react with these materials. Oxidation can change the chemical structure of the substances, leading to a loss of potency. Moisture can cause clumping, mold growth, or hydrolysis, which breaks down the compounds.
When you first notice that your raw materials have been exposed to air, the very first step is to assess the damage. Take a close look at the physical state of the product. Is there any visible discoloration? For example, if it was originally a white powder and now it has a yellowish tint, oxidation might be occurring. Check for clumps; if the material has turned into lumps, moisture could be the culprit.
Once you've done the assessment, if the exposure has been minimal, you might be able to salvage the product. For dry powder - like raw materials, you can try to sift them. Use a fine - mesh sieve to break up any small clumps and remove any large, affected chunks. This can help to restore the powder's original texture and improve its flowability.
For liquid raw materials, things are a bit more tricky. If the liquid has become cloudy or has developed an unusual odor after air exposure, it's a sign that chemical changes have taken place. In some cases, you can try to filter the liquid through a high - quality filter paper to remove any suspended particles. But if the odor is really strong or the color change is significant, it might be best to discard it.

Now, let's talk about storage after air exposure. The key is to create an environment that minimizes further contact with air. For dry materials, transfer them to air - tight containers as soon as possible. You can use glass jars with rubber seals or plastic containers designed for chemical storage. If you have access to nitrogen gas, you can flush the container with nitrogen before sealing it. Nitrogen is an inert gas, which means it won't react with the raw materials and can displace the oxygen in the container.
For liquid raw materials, make sure the storage bottles have tight - fitting caps. You can also consider storing them in a refrigerator if the product specifications allow it. Lower temperatures can slow down chemical reactions and reduce the rate of oxidation.
Let's take a look at some specific veterinary raw materials and how to handle them after air exposure. One common raw material is 4 - bromopyridine Hydrochloride CAS 19524 - 06 - 2. This compound is sensitive to moisture and air. If it has been exposed to air, quickly transfer it to an air - tight container. You can place a desiccant packet inside the container to absorb any remaining moisture. Desiccants like silica gel are great for this purpose.
Another important raw material is Dehydroepiandrosterone | CAS 53 - 43 - 04. It can oxidize when exposed to air. To prevent further oxidation, store it in a cool, dark place. If possible, keep it in a container filled with an inert gas like argon or nitrogen.
[Ethyl - 2 - ethoxy - 1 - [(2 - (1Htetrazol - 5 - yl)biphenyl - 4 - yl - ) Methyl] CAS#139481 - 58 - 6 is also a sensitive compound. After air exposure, if it's a solid, you can try to recrystallize it. Dissolve the affected material in a suitable solvent (according to its solubility properties), heat the solution gently, and then let it cool slowly. This can help to purify the compound and remove any impurities formed due to air exposure.
It's also crucial to keep detailed records. Note down the date and time of air exposure, the duration, and any visible changes you observed. This information can be very useful for future reference, especially if you need to explain the condition of the product to your customers or if you want to improve your handling procedures.
When it comes to handling large - scale air - exposed raw materials, you might need to consult with a chemist or a quality control expert. They can provide more in - depth analysis and suggest advanced treatment methods.
In some cases, despite your best efforts, the product might still be too damaged to use. It's important to have a proper disposal plan. Follow local environmental regulations for disposing of veterinary raw materials. Don't just dump them in the regular trash, as they could be harmful to the environment.
