These coenzymes act as cofactors for methionine synthase and methylmalonyl-CoA mutase, linking B12 to one-carbon metabolism, DNA methylation, myelin maintenance and red blood cell formation. Because of its stability, cyanocobalamin is commonly used as a reference form in cellular metabolism models and in comparative studies against methylcobalamin and other cobalamin forms.\u003c\/p\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompound:\u003c\/strong\u003e Vitamin B-12 (Cyanocobalamin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCAS number:\u003c\/strong\u003e 68-19-9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAppearance:\u003c\/strong\u003e Lyophilised red powder\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePurity:\u003c\/strong\u003e 99%+ verified by HPLC-MS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAvailable size:\u003c\/strong\u003e 10mg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePresentation:\u003c\/strong\u003e Sealed, tamper-evident vial\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTesting and verification\u003c\/h2\u003e\n\u003cp\u003eEvery batch is independently analysed by a third-party laboratory using HPLC-MS to confirm identity, quantity and purity.
