For your RFQ, pricing breaks down cleanly at three tiers: sample size around 50mg runs about $45, mid-range 100mg comes to $75, and bulk 500mg is $250—basically the cost per mg drops by nearly 40% form sample to bulk, so if you're running multiple assays, teh 100mg or 500g is where you'll see real savings.
We're offering 99% purity by HPLC on this reduced glutathione powder, CAS 70-18-8, with a molecular weight of 307.32 g/mol, and it's water soluble, which makes reconstitution straightforward for your cell work or redox studies; just keep it at 2-8°C (we usually have stock, but confirm lead time for larger orders).

One thing buyers often ask about is the 5mg to 60mg range—we can customize the fill, but most go with the 10mg or 15mg vials for standdard, and the 20mg is a solid middle ground if you're not sure yet.

It's not ideal for long-term storage at room temp, so plan to aliquot and freeze if you're not using it within a week or so; that's a common gotcha with reduced glutathione since it oxidizes over time.

The white powder itself handles well—no clumping, and it dissolves cleanly in water at about 50 mg/mL without much stirring, which is a detail you'd only know after handling a few batches.
So for your order, our company can do the 100mg at $75 with a COA included; let me know if you need the SDS or TDS, and we'll ship within 3-5 business days.
