Is Cyanocobalamin the same as every material sold as Vitamin B12?

No. Cyanocobalamin, CAS 68-19-9, is one defined cobalamin form. Methylcobalamin and hydroxocobalamin are different substances, while some Vitamin B12 products are diluted preparations. Confirm the exact cobalamin form, CAS number, potency basis and grade before comparing specifications or prices.

How does pure Cyanocobalamin differ from a 0.1%, 1% or 5% Vitamin B12 premix?

Pure crystalline Cyanocobalamin is specified on a high-assay, often dried-substance basis. A premix contains a stated proportion of Cyanocobalamin on a carrier and is purchased by potency, carrier, particle size, homogeneity and microbiological or contaminant limits where applicable. The two forms are not comparable kilogram for kilogram.

Which grade and documents should be requested for bulk Cyanocobalamin?

State the intended food, feed, pharmaceutical, compendial or industrial formulation use and destination market. The specification may need assay or potency, identification, related substances, loss on drying, elemental impurities and microbiological limits. Confirm the applicable COA, TDS, SDS, compliance documents, light-protective packing and storage conditions for the offered grade.

Cyanocobalamin (Vitamin B12) CAS 68-19-9

Cyanocobalamin , CAS 68-19-9 and EC 200-680-0 , is the cyanide-ligated form of vitamin B12 with molecular formula C63H88CoN14O14P and molecular weight 1355.4 g/mol. It is not methylcobalamin or hydroxocobalamin. Grade selection should follow the intended food, feed, pharmaceutical, analytical or formulation use and must be supported by the relevant specification. Buyers should request potency or assay, related substances, moisture, residual solvents, microbiological limits where applicable, particle characteristics and compendial or regulatory status.

Item	Technical guidance
Product identity	Cyanocobalamin; vitamin B12
CAS / EC	68-19-9 / 200-680-0
Formula / molecular weight	C₆₃H₈₈CoN₁₄O₁₄P / 1355.4 g/mol
Identity boundary	Cyanocobalamin, not methylcobalamin, hydroxocobalamin or another cobalamin form
Key purchase controls	Identity, potency or assay basis, related substances, moisture, residual solvents, microbiology where applicable, particle properties and grade documentation

Applications and grade selection

Cyanocobalamin may be evaluated for food, feed, pharmaceutical, premix, research or analytical use only when the offered grade, concentration, carrier system and regulatory documentation match that use. A nominal 99 percent industrial-grade label is not an adequate purchasing specification.

Confirm whether the offer is neat cyanocobalamin, a triturated product, premix or another formulation.
Match the specification to the required compendial, food, feed or analytical standard.
Evaluate potency, homogeneity, stability, particle behavior and formulation recovery in the intended matrix.

Storage and handling

Store tightly sealed and protected from light, heat and moisture under the conditions stated for the exact grade. Control opening time and sampling, and follow the documented retest or expiry period.

Safety, documentation and procurement

Use hygienic handling and suitable dust control. Procurement should state grade, potency basis, carrier or concentration, quantity, package, destination, regulatory market, shelf-life needs and required documents.
