Impurity reference standards in the pharmaceutical industry play a significant role in ensuring the effectiveness and safety of drugs. These standards act as reference materials for quantifying, controlling, and identifying impurities in several medicinal products. Thus, providing complete and accurate details while inquiring about the same is important.
We understand you may need to be informed of the details or information you should include. Thus, this blog sheds light on the most important details. So, let’s begin!
IUPAC, or the Chemical Name of the Impurity
The impurity’s IUPAC or chemical name helps in identifying the correct standard needed. Additionally, it also allows impurity reference standards suppliers to share valid information concerning their price and availability. Generally, this information is available in pharmacopeia (only if it contains the resources needed for a particular product).
Chemical Structure
Notifying the supplier about the exact chemical structure of the impurity will help them determine the accurate impurity standard needed.
Impurity’s CAS Number
CAS, an acronym for Chemical Abstracts Service, is a unique number allocated to chemicals. Similar to the chemical structure, if the CAS number is available and mentioned, the supplier can find the relevant impurity standards requested.
Purity Level
Important information like purity level should be stated in the inquiry as it helps the supplier choose exact standards that match particular requirements. Please note that a few impurities may demand high purity standards based on their regulatory requirement.
Delivery Timeline and Location
Accurate delivery details concerning timeline and location help suppliers determine the cost of shipping along with the tentative delivery date. Thus, it is essential to provide these details to avoid any confusion or delay in the shipping process.
Quantity
There is a possibility that the supplier might not be able to arrange impurity reference standards at the last minute. Therefore, be smart and inquire about the exact quantity you require to avoid any last-minute hassles.
Purpose
Different impurity standards are used for different purposes. While some may be appropriate for analytical purposes, some are for research purposes. Therefore, it is crucial that you mention the use case since it will help the supplier decide on the standard’s suitability for a specific purpose/application.
Regulatory Requirements
Information concerning regulatory requirements should be clearly stated in the inquiry. It is because impurity standards might need to meet certain standards like USP (United States Pharmacopeia) or EP (European Pharmacopoeia). If mentioned, the supplier can make sure to send the standard meeting those regulatory requirements.
Quality Documentation
Quality documentation can include material safety data sheets, analysis certificates, and more such documents. They help customers to make sure that impurity standards meet the desired quality. So, don’t forget to ask for quality documentation at the time of inquiry.
Wrapping Up
While sending inquiries about impurity reference standards, it is vital to provide in-depth information to ensure that providers can deliver appropriate standards. It also helps customers receive quality service and high-quality reference standards that meet their criteria.
