Chromium Picolinate Powder | USP/EP Compliant

What Is クロムPicolinate粉 (USP/EP Compliant)?

Chromium Picolinate Powder (USP/EP Compliant) is a high-purity organometallic coordination complex synthesized through the precise linkage of trivalent chromium (Cr³⁺) with three picolinic acid ligands. Functioning as an identity-verified active nutritional substrate, the material is engineered strictly for integration into human dietary supplements, capsule compoundings,とpharmaceutical-grade metabolic health formulations.

The chemical manufacturing architecture ensures that the crystalline substance achieves an active trans-isomer monomeric purity of 98.0% to 102.0% calculated on a dried basis, fully complying with United States Pharmacopeia (USP) and European Pharmacopoeia (EP) compendial monographs. Testing protocols utilize validated Reversed-Phase HPLC and Atomic Absorption Spectrophotometry (AAS) to verify ligand-to-metal chelation integrity.

Engineered with a stable tapped bulk density controlled within 0.48 g/mL to 0.62 g/mL, the reddish-purple crystalline powder delivers predictable volumetric die filling uniformity during high-speed encapsulation runs exceeding 60,000 capsules/hour. Restricting total Loss on Drying to ≤ 3.0% via USP <731> eliminates mechanical punch filming and prevents raw material agglomeration under climate-controlled storage environments.
