Description
Our HA-966 liquid is HA-966 supplied as a measured liquid solution. Each batch is tested by LC-MS to 99% purity or higher. It’s $99.99. It’s sold for laboratory research only.
The same compound comes in other formats too: HA-966 powder and HA-966 capsules. You’ll find similar products in our nootropic liquids range.
What is HA-966?
HA-966 (3-amino-1-hydroxypyrrolidin-2-one) acts at the glycine site of the NMDA receptor. Its two enantiomers behave differently: the (R) form is the glycine-site ligand, while the (S) form is a strong sedative.
It’s sold here as the hydrochloride.

How to use the HA-966 liquid
HA-966 liquid is pre-dissolved at 25mg/mL, which makes measuring simple: you work in volumes instead of weighing tiny amounts of powder.
Use a clean graduated pipette or dropper for each draw so nothing goes back into the bottle. Shake gently first, because some solutions settle over time. We stock transfer pipettes and dropper bottles if you need them.
Making working dilutions of HA-966
If your protocol calls for a lower concentration, dilute a measured volume into a clean glass bottle. For example, 1mL of the 25mg/mL solution plus 1mL of carrier gives 2mL at 12.5mg/mL. Use the same carrier where possible, or a solvent your protocol allows, and mix gently.
Make up only what you’ll use in the short term, and label the new bottle with the concentration and date.
Purity testing for HA-966
We test each batch of HA-966 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.
Storing your HA-966
Keep it in a cool, dry place away from direct sunlight. Keep the cap tight so the solution doesn’t evaporate or pick up contaminants. Label anything you decant with the compound, amount and date, and keep it out of reach of children and pets.
