The purity is displayed in the technical data section of the online product information page, representing the minimum content of active ingredients contained in any batch of products. Due to differences in manufacturing processes, there may be slight differences in purity between batches, but these differences have no impact on the biological characteristics of the material.

Biological activity chemical purity

The purity of Jiangheng active chemicals is very high, and the purity measured by HPLC is usually>99%. For the purity of specific products, please refer to the Batch Analysis Certificate (CoA).

Isotope purity

Isotope purity is the percentage of stable isotopes in the product.

Peptide purity

Unless otherwise specified, the peptide purity provided by Jiang Heng is>95%. For the purity of specific products, please refer to the Batch Analysis Certificate (CoA).

Quality Control

The purity of chemicals is evaluated through a series of techniques, including HPLC, chiral HPLC, NMR, microanalysis, high-pressure electrophoresis, melting point, optical rotation, TLC, and mass spectrometry, with specific methods selected based on material properties. All data is recorded and can be checked upon request - please contact us for details. We believe that the purity of any material provided by Jiang Heng will not be lower than the product purity initially reported in scientific literature.

The half-life of a drug in the body (t ^ 2) refers to the time when the concentration of the drug in the plasma decreases to half of its initial value. If the half-life of a certain compound is known, we will publish it in the product's biological description. Due to the cutting-edge nature of some Tocris products, half-life information may not be available in published literature. Therefore, we cannot guarantee to provide a definite half-life value for the product.
