Chemical manufacturing and synthesis services produce organic chemicals and inorganic chemicals on a contract, toll, customized, or research and development basis. Chemicals are building blocks for industries such as petrochemical processing to pharmaceutical manufacturing. Chemical synthesis involves the conversion of raw materials into different or more usable molecules. Catalysis is the process of slowing or speeding up chemical reactions by adding a substance that is not changed in the reaction process. Typically, large amounts of heat and energy are required.

Chemical manufacturing and synthesis services may specialize in the processing of a particular type of organic chemical, industrial organic chemical, or synthetic organic chemical. Chemical manufacturing and synthesis services provide intermediates, reference compounds, starting materials, or derivatives of compounds. Scientists, engineers and other technical personnel who work for chemical manufacturing and synthesis services are trained in disciplines such as synthetic organic chemistry, analytical chemistry, or biopolymer chemistry. Some chemical manufacturing and synthesis services work on a toll or fee basis. These toll processors may hire operators to run the process equipment, or rent or lease their facility to a client who can bring in trained personnel. Employees can also perform processes such as distillation, drying, mixing, blending, purification, extraction, synthesis, or milling of chemicals, powders and bulk materials on a contract basis.

Providers of chemical manufacturing and synthesis services adhere to regulatory requirements and meet various quality standards. In the United States, relevant regulatory agencies include the Environmental Protection Organization (EPA), the Occupational Safety and Health Administration (OSHA), and the Food and Drug Administration (FDA). A chemical manufacturing service with a test laboratory typically has a testing facility or system assessment that is certified or qualified to meet the requirements of ISO 7779, ISO 9000, ISO 13485, ISO 14000, ISO 17025, ISO / TS 16949, QS 9000, TE supplement, and TL 9000.  Additional certifications include ASME approvals, NRTL recognition and  A2LA, NVLAP, or NADCAP accreditation.
