D-Pantothenic Acid Calcium Salt
Calcium D-pantothenate is the calcium salt of D-pantothenic acid (Vitamin B5), a water-soluble vitamin essential for coenzyme A synthesis. This chemically defined derivative is classified under HTS 2936.24.0100 as a derivative of D-pantothenic acid used primarily as a vitamin in supplements and fortified foods.
DL-Pantothenic Acid
DL-Pantothenic acid is the racemic mixture of D- and L-isomers of Vitamin B5, used in pharmaceutical and nutritional applications. As a synthetic provitamin explicitly covered by HTS 2936.24.0100, it qualifies as an unmixed vitamin derivative for human and animal nutrition.
Dexpanthenol (Provitamin B5)
Dexpanthenol, the alcohol analog of D-pantothenic acid, converts to pantothenic acid in the body and is used in cosmetics and pharmaceuticals. This derivative falls under HTS 2936.24.0100 as a pantothenic acid derivative used primarily as a vitamin/provitamin in skincare and wound healing products.
Rac-Pantothenic Acid Sodium Salt
Sodium rac-pantothenate, the sodium salt of DL-pantothenic acid, serves as a water-soluble Vitamin B5 derivative for oral supplements. Classified under HTS 2936.24.0100 per Chapter Note 5(C)(1) for inorganic salts of organic vitamin compounds used primarily as vitamins.
Panthenol USP Grade Powder
Pharmaceutical-grade D-panthenol powder meeting USP standards for use in injectables and oral supplements. As a high-purity derivative of pantothenic acid used primarily as a provitamin, it precisely matches HTS 2936.24.0100 specifications for unmixed vitamin derivatives.
Calcium Pantothenate 98% Feed Grade
Feed-grade calcium D-pantothenate at 98% purity for animal nutrition fortification. Despite animal feed application, classification remains HTS 2936.24.0100 as an unmixed vitamin derivative per Chapter 29 notes, not Chapter 23 preparations.
DL-Pantolactone
DL-Pantolactone, the cyclic internal ester (lactone) of pantothenic acid, serves as a provitamin B5 intermediate that hydrolyzes to pantothenic acid. Covered under HTS 2936.24.0100 as a pantothenic acid derivative used primarily in vitamin synthesis.
D-Panthenyl Alcohol
D-Panthenyl alcohol, a reduced form of pantothenic acid derivative used in hair care and skin moisturizers. Qualifies under HTS 2936.24.0100 as it functions primarily as a provitamin B5 despite cosmetic applications.
Pantethine (Pantothenic Acid Dimer)
Pantethine, the dimeric disulfide form of pantothenic acid, used for cholesterol management and antioxidant support. As a derivative used primarily for vitamin-like metabolic functions, it falls under HTS 2936.24.0100 specifications.
