Fine chemicals are single, pure chemical compounds with precise properties that result in an end product. Commodity chemicals are used to make fine chemicals. These are utilized as organic building blocks to generate new compounds with particular functional properties. Fine chemical production is complicated and variable, with multi-step operations using new technology to reach ultra-high purity criteria.
