ã€Molecular Weight】450.7
ã€Assay】97.0~103.0%
ã€Quality Standard】USP42 Pharm.Grade
ã€Packing Size】1KG/tin, 5KGS /tin,
ã€Storage】Tight container, protect from light
Vitamin K exists as an oily liquid or solid and it cannot dissolve in water. However, it can easily dissolve in organic solvents like oils and ethers. This vitamin is known for its chemical stability, resistance to heat and acids. Sadly, it is sensitive to alkali and ultraviolet rays, leading to easy decomposition. Vitamin K holds great importance in promoting normal blood coagulation and supporting bone growth. Regrettably, it is often deficient in newborns and its requirements for humans are quite low. Luckily, it can be easily supplemented through daily diet by consuming dark green vegetables and yogurt.

UV spectrum | The maximum values for absorption in the test solution and standard solution occur at the same wavelength of 248 nm, and the absorptivity at this wavelength in the test solution is within a 3.0% range compared to the standard solution. Let's rearrange the above information to create a highly similar content: The test solution and standard solution both exhibit their highest absorption peaks at 248 nm, indicating that both solutions reach their maximum absorption at the same wavelength. Furthermore, the absorptivity of the test solution at 248 nm remains within an acceptable range of 3.0% when compared to the absorptivity of the standard solution at the same wavelength. |
Infrared spectrum | Conforms to standard spectrum |
Reaction 1 | Dehydrated Alcohol, when mixed in a 1 in 20 solution, shows neutrality to litmus. To reiterate, the solution remains unchanged in terms of litmus reaction despite the presence of this particular concentration of dehydrated Alcohol. |
Reaction 2 | Test the limit of menadione |
Refractive index | 1.523~1.526 |
 Appearance | This highly viscous, oily liquid is a vibrant shade of intense yellow. It exhibits practical insolubility in water and limited solubility in alcohol, but readily mixes with fatty oils. |

Function
Vitamin K is a stable and heat-resistant nutrient that can be found in dark green vegetables and yogurt. It is an oily liquid or solid that is insoluble in water but soluble in organic solvents like oils and ethers. This vitamin is critical for promoting normal blood coagulation and bone growth, making it an important nutrient for both adults and newborns. However, it can easily be deficient in newborns due to low requirements in humans. Vitamin K is resistant to acid and heat, but it can be decomposed by ultraviolet rays and alkali. Therefore, it is crucial to ensure adequate intake of vitamin K through a balanced and healthy diet.
