How Can You Identify Impurities?

by Brock Tebbutt

Prospective toxic chemicals coupled with carcinogens found in drugs which are supposed to treat diseases are the biggest issues that have plagued the pharmaceutical ingredient manufacturing. For that reason and more, one of the most crucial tasks of a contracting manufacturing company is identifying impurities before impacting the quality and efficacy of the drugs being produced and their safety. Well, this is a costly project that needs the input of experts. So how do you identify impurities in a compound?

How To Analyze Levels Of Impurities

Analyzing the varying levels of impurities coupled with the physical and structural attributes helps in identifying the cause of different variations in the actual finished products, especially during the drug development stages and formation. It is also very important in determining the potential issues when evaluating the new suppliers while changing as well as adding manufacturing sites.

 Typically, the value of information and data gleaned from the analysis is highly dependent on the tests carried out. But the bottom line is that all too often, spending some time analyzing the samples to identify the impurities prior to making manufacturing decisions is a strategy towards saving time as well as making more money. This is also a method towards cutting down costs.  

Defining And Understanding Chemical Impurities

Chemical impurities refer to various chemical substances in a sample that different from the actual chemical composition of that compound you are interested in. Typically, the impurities are naturally occurring and are formed in the process of synthesizing a chemical compound.

It is valuable to note that it is impossible to relatively have that molecular substance, which is usually 100 percent pure as well as free of various impurities. The objective for most drug and chemical manufacturers is to exceed the range of 99 percent significantly.

Impurities Found In Raw Materials

Because raw materials have some level of impurity, it is crucial to vet your suppliers to make sure that they are of high quality. Most of the CMOs will perform their tests in advance on different raw materials to determine the condition before purchasing. And when raw materials are considered, CMOs will go ahead and ask for a viable sample before conducting the quality test. This is intended to help ensure that it meets the demands requirements.

Checking Impurities In The Process Of Manufacturing

It is also essential to check impurities, including where they hail from through a trusted process. Perhaps there is a way you can look at it, and it includes taking samples of A and B and then comparing the molecules as they undergo a chemical reaction.

While the majority of these molecules are going to orient themselves in order to create B, there are times when they end up creating material D. In most cases; this is an example in the process of impurities. Many firms will often strive for about 80 percent. The other will strive to have a higher percentage.

Final Thoughts – Risk Evaluation

 It is crucial to conduct risk evaluation when checking the chemical impurities of a product. During the root cause analysis, you need to evaluate the effect of contamination on the drugs or chemical substances you have.
