Is Product C6144, Chlorophyll a, soluble in solvents other than diethyl ether?
This product is soluble in ethanol (10 micrograms/mL). It is also freely soluble in acetone, benzene, and chloroform, but is not soluble in water. However, its spectral characteristics are most well characterized for solutions in diethyl ether.
Can Product C6144, Chlorophyll a, be used as an analytical standard?
We do not recommend using this product as a standard. The fill weights of 1 mg and 5 mg are minimum values and are not guaranteed to a specific precision. Also, the product is not traceable to a consensus standard reference material.
What is the purity of Product C6144, Chlorophyll a, as determined by chromatographic analysis (e.g., by HPLC)?
We do not determine the purity of Product No. C6144 by chromatographic means. We offer an HPLC tested Chlorophyll a (isolated from spinach) as Product no. C5753.
How does chlorophyll a from blue green algae differ from that found in plants?
A complete analysis of chlorophyll a between species would require extensive study. We can say that the CAS number of this product is the same as that for chlorophyll a from spinach, a typical green plant.
