N6-(delta 2-Isopentenyl)-adenine Peptide Site CAS 2365-40-4 | High Purity Pharmaceutical Intermediate

If you’re sourcing for a research lab in UK that’s pushing into cytokinin studies, you’ve probably run into this one. We’ve shipped enough to know the import docs for CAS 2365-40-4 usually go through fine as long as the COA and SDS are attached—those customs folks can be picky. So I’d recommend confirming your local phytosanitary requirment early, especially for EU destinations where regulations shift more often than you’d think.

It’s an off-white crystalline powder with a molecular weight of 351.36, and we’ve tested it to 99%+ purity—actually, we saw 99.3% on the last batch. Solubility is a clear colorless to faint yellow solution at 10mg/ml in 1N HCl, which is decent for most bioassays. The acute oral toxicity (mouse LD50) sits above 10g/kg, so it’s about as safe as these things get for research use. That CAS number is 2365-40-4, but you probably already knew that.

One buyer uses it mainly to stimulate callus differentiation and induce bud formation in apples and pears, then branches out into roses and grapes for fruit-set enhancement. It’s not great for everything though—we’ve found it underperforms on leafy greens like lettuce, where auxins work better anyway. A lot of people in the US pair it with gibberellic acid, and teh is pretty solid for tomato yields, but I’d test your own cultivars first.

Anyway, ordering’s straightforward—MOQ is typically 50 grams or so, and we keep roughly 5kg in stock for quick dispatch form US and EU warehouses. Check lead time (usually 2-4 weeks) if you need a custom lot size.
