Tips for measuring NSI-189 powder
Buying NSI-189 as a powder gives you full control. Weigh out exactly what your protocol calls for, make up your own solutions, or encapsulate it yourself.
For small amounts you’ll want a scale that reads to at least 0.01g, and ideally 0.001g. Our digital scale and micro scoops make it easier to get consistent measurements. Weigh onto clean weighing paper, and close the bag or jar straight after so the powder doesn’t pick up moisture.
Making a solution from NSI-189 powder
To make a stock solution, decide on the final volume and concentration first. For 30mL at 10mg/mL you’d weigh 300mg of NSI-189, dissolve it in about 25mL of solvent, then top up to exactly 30mL.
Check the compound’s solubility in your chosen solvent before you start, and try a small test amount first. Store the finished solution in a labelled glass bottle.
How we test NSI-189
We test each batch of NSI-189 by LC-MS, which pairs liquid chromatography with mass spectrometry. The chromatography splits the sample into its components and the mass spectrometer identifies them, which tells you both identity and purity. This batch came in at 99% or higher.
Small differences between batches are normal, so write the batch number from the label into your records. If something looks wrong when your order arrives, like discoloured powder or a cloudy solution, set it aside and don’t use it.
How to store NSI-189
Keep it refrigerated. Use a clean, dry scoop each time, and reseal the container straight away. Label anything you decant with the compound, amount and date, and keep it out of reach of children and pets.
Common questions about the NSI-189 powder
What can I dissolve NSI-189 powder in?
That depends on the compound’s solubility and your protocol. Check the solubility data for your solvent first, and test a small amount before making up a full batch.
What scale do I need?
One that reads to 0.01g at minimum, and 0.001g for very small amounts. Our pocket scale reads to 0.01g.
