Molecular Purity

Meaning

Molecular Purity is a rigorous quality control metric that quantifies the concentration of the desired active pharmaceutical ingredient (API) or hormone relative to the presence of any impurities, contaminants, or related substances within a final product. This measure is absolutely critical in the context of hormonal health, particularly for compounded or bio-identical preparations, as even trace amounts of unwanted isomers or manufacturing byproducts can alter efficacy or introduce toxicity. Achieving high molecular purity is the standard for ensuring the safety, potency, and predictable clinical performance of any therapeutic agent.
