Product Overview

Methylcobalamin is the active coenzyme form of Vitamin B12 used as a research compound in controlled laboratory environments. Its well-characterized molecular structure and role as a methyl-group donor have made it a widely studied material in cobalamin chemistry and methylation research. Researchers use Methylcobalamin when examining cobalamin chemistry, methylation cofactor behavior, and micronutrient research modeling under controlled conditions. Supplied as a lyophilized powder for laboratory preparation. Store dry material in a cool, dry environment away from direct light. Once reconstituted, refrigerate or freeze at -4°F for extended storage. Each batch is produced to pharmaceutical-grade standards. Strictly designated for in vitro and laboratory research use only.
