Pharmacopoeia

Waste materials and any surplus or old reagents must be treated according to the relevant regulations.

Use

The Reagents supplied by Clearsynth, except those with specific descriptions, such as food colors approved by the Food Sanitation Law (product grade FC in our catalogue) and known bulk pharmaceuticals, are intended to be used for research and development. They cannot be used to produce pharmaceuticals, quasi drugs, cosmetics, agricultural chemicals, insecticides or food additives. Under no circumstance are they intended for use in the home. When improper use is suspected, Clearsynth reserves the right to refuse to supply any product, as is also dictated by law, and takes no responsibility for any improper use.

Our reagents may contain items regulated by local laws; for example TSCA (Toxic Substances Control Act) or the New Chemical Substance law. Please contact your local Clearsynth office or distributor, or your local regulatory office, for more details.

When controlled substances are sold or purchased for testing and experimental purposes, details of the buyer's appropriate license or qualification, or a predetermined procedure based on the related regulations, may be required.

Clearsynth does not guarantee that a new chemical substance manufactured by using our reagents, or that using our reagents in combination with other products, or using them in certain procedures does not infringe on any patents of Japan or foreign countries. It is the buyer's responsibility to ensure that no patents are infringed.
