What is chemical grade?
The chemical grade is the quantification that indicates the purity of a chemical. The chemicals that are free from other chemicals, water, metals, or any other impurities, or have a minimum quantity of these impurities are referred to as higher grades of chemicals with high purity; while the ones with greater impurities are the lower grade. Manufacturing of higher-grade chemicals involves tedious processes and are often time-consuming, hence, the higher-grade chemicals are expensive than the lower grade chemicals.
Chemical grades hold a special significance in the manufacturing and testing of pharmaceutical products and other healthcare chemicals. It is important to use chemicals of the highest purity in the pharmaceutical and healthcare applications as it is directly linked to the wellbeing of the masses. It is a common practice for the manufacturers to ensure that all the regulatory standards and compliances are met for the intended use.

Different types of Chemical Grades?
Chemical grades are important in all industrial and pharmaceutical constituents as they define the quality standards of the chemical, which is applied for specific uses like in food and medicine. Furthermore, the choice of the right grade of reagent is essential to attain precision, which is of utmost importance in the testing procedures. Based on the requirement, the correct grade of reagent can be picked which will offer accurate results of your testing.
Based on the percentage of purity and their applications, chemical grades are classified into different types; the most common types are discussed below.
The most common chemical grades include:
- ACS Grade
- Analytical grade
- USP Grade
- NF Grade
- Lab Grade
- Purified Grade
- Technical Grade
Chemicals are often labeled with grades representing their purity. The grading terms may sometimes differ from one manufacturer to the other, but the general chemicals grades are the ones listed above. So, check the grade as per your requirement before purchase.
ACS grade chemicals
ACS grade meets or exceeds the purity standards set by the American Chemical Society (ACS). It includes the chemicals with high purity that requires strict quality specifications and purity great than or equal to 95%. Such a high purity range makes them suitable for use in food and medicine. It is also the perfect choice for analytical applications and experiments involving biological matters.
What are Analytical Grade Chemicals?
Based on the purity, the analytical grade is usually similar to ACS grade with the highest purity; the purity greater than or equal to 95%. The reagent grade is also suitable for use in food, drug, or medicinal applications, in addition to their use in many other laboratory and analytical applications, and experiments involving biological matters.
Analytical grade is commonly referred to as Reagent grade, UNIVAR, Guaranteed Reagent (GR), AnalaR, and Premium Reagent (PR).
USP grade chemicals
The USP grade has adequate purity to meet or exceed the requirements of the United States Pharmacopeia (USP). It is acceptable for food, drug, or medicinal use; often used for laboratory purposes too. The USP use should be reviewed before use to ensure that the grade is appropriate for the process being conducted.
NF grade chemicals
NF grade has sufficient purity to meet or exceed the requirements of the United States National Formulary. This provides the standards of manufacturing, pharmaceutical, and other chemical processes; the information is updated annually and published in USP-NF (United States Pharmacopeia-National Formulary). The NF and USP were, previously, two separate entities, but merged in the 1970s.
For a product to have an NF grade, the product is required to meet the specifications of the NF monograph. It is to be noted that if there is no study conducted for the product by the NF, it cannot be labeled as NF grade.
The purified grade, also known as a pure or practical grade, has no precise definition that meets any official standards. It is not pure enough to be used for food or drug.
Technical grade chemicals have normal purity due to the presence of a small amount of other chemicals. They are popularly used for commercial and industrial purposes, however not suitable for use in food and medicine.
What are Lab Grade Chemicals?
Lab grade has a relatively high purity but also contains some impurities, the exact amount of which is often unknown. They are not suitable for food or medicine, but are the popular grade used in teaching and educational labs. They often meet the standards of British Pharmacopoeia (BP) or USP (United States Pharmacopoeia). Generally, the complete product specification is available.
What are Food Grade Chemicals?
A food-grade chemical is referred to as an additive that is non-toxic and safe for consumption. They are added to the product to primarily modify the taste and texture of the food. They are compliant with health and safety regulations and international standards.
Common food grade chemicals are:
- Food preservatives
- Artificial food coloring
- Artificial flavoring
- Vitamins and minerals
What are GPR Grade Chemicals?
GPR grade chemicals generally include pure reagent-grade chemicals and pure reagent chemicals. It is claimed that these grade chemicals have a purity rating of up to 99.9%; it is to be noted that these products do not undergo stringent testing for impurities and other contaminations. This makes them unsuitable for use in food and drugs. However, they are popularly used in the general chemistry laboratory and schools and other educational institutions.
