Riboflavin Sodium Phosphate is a water-soluble derivative of vitamin B2 (riboflavin) designed mainly for medical and injectable use where rapid, reliable vitamin delivery is needed.
1. Identity
- Name: Riboflavin Sodium Phosphate
- Category: Vitamin derivative (Vitamin B2 form)
- Parent compound: Riboflavin (Vitamin B2)
- Active vitamin form precursor: FMN (Flavin Mononucleotide), FAD (Flavin Adenine Dinucleotide)
- Type: Phosphorylated sodium salt of riboflavin
2. Chemical nature
- Modified riboflavin molecule with a phosphate group
- Formed as a sodium salt to improve solubility
- Highly water-soluble compared to plain riboflavin
- More suitable for aqueous pharmaceutical solutions (especially injections)
3. Physical properties (general)
- Appearance: Yellow to orange-yellow powder or solution
- Solubility: Highly soluble in water
- Stability: More stable in solution than riboflavin under clinical storage conditions
- Sensitivity: Light-sensitive (like other riboflavin compounds)
4. Biological role (after administration)
Once administered, it is rapidly converted into:
- FMN (Flavin Mononucleotide)
- FAD (Flavin Adenine Dinucleotide)
These are essential cofactors involved in:
- Cellular energy production (mitochondrial respiration)
- Oxidation–reduction (redox) reactions
- Fat, carbohydrate, and protein metabolism
- Antioxidant enzyme systems
5. Primary purpose
It is used mainly as a:
- Clinical vitamin B2 source
- Injectable nutritional supplement
- Medical-grade riboflavin replacement form
6. Common forms of administration
- Intravenous (IV) injections
- Intramuscular (IM) injections
- Included in parenteral nutrition (TPN)
- Occasionally used in hospital vitamin infusions
7. Key characteristics summary
- Highly bioavailable injectable vitamin B2 form
- Rapidly converted into active coenzyme forms (FMN/FAD)
- Designed for clinical use rather than dietary supplementation
- Essential in hospital nutrition and deficiency correction
8. Main limitation
- Not typically used as a standalone therapeutic drug
- Primarily serves as a supportive metabolic vitamin in medical settings
If you want, I can also compare it directly with riboflavin (oral form), FMN, and FAD, or explain its industrial manufacturing and synthesis pathway in pharmaceutical production.
