Description
The pure D-enantiomer of Calcium Pantothenate, Vitamin B5. The same active as our standard Calcium D-Pantothenate listing, traded specifically under the D-Calcium Pantothenate chemical name for buyers distinguishing it from the racemic DL-Calcium Pantothenate variant used in feed.
White to slightly yellowish crystalline powder. Slightly hygroscopic; freely water-soluble. Only the D-enantiomer is biologically active in humans, making this form mandatory for human nutrition, supplements, and pharmaceutical applications.
We supply food-grade and pharmaceutical-grade D-Calcium Pantothenate from manufacturers in China holding ISO, Halal, Kosher and other certifications relevant to the product and production.
Common market grades include Food Grade FCC-compliant, Pharmaceutical Grade meeting BP/USP/EP/JP monographs, and DC (direct-compression) grade for solid-dosage manufacturing. The DL-Calcium Pantothenate racemic variant is sold separately for feed use only.
Bulk and reduced-MOQ shipments. Batch-level COA covering assay, specific rotation (the marker confirming D-isomer purity), calcium content, heavy metals, and microbiology.
Introduction
D-Calcium Pantothenate is the optically pure D-enantiomer of calcium pantothenate, distinguished from DL-Calcium Pantothenate (the racemic mixture used in some feed applications). Only the D-isomer is biologically active; the L-form has no vitamin activity and is treated as an inactive ingredient.
Industrial production proceeds by chemical synthesis with asymmetric resolution or enzymatic separation to yield pure D-pantolactone, which is condensed with calcium beta-alaninate to produce the D-calcium pantothenate salt directly without racemization.
Listed in BP, USP, EP, and JP pharmacopoeias as Calcium Pantothenate, with specific rotation specifications that effectively require the D-form. Recognized as a permitted food ingredient by the U.S. FDA and the European Food Safety Authority.
This SKU is traded under the D-Calcium Pantothenate chemical name specifically to allow buyers to distinguish it from DL-Calcium Pantothenate at order entry. Nutritional content and applications are otherwise identical to the standard Calcium D-Pantothenate listing.
