154947-66-7 is the CAS, and this one typically comes in at >99.9% by HPLC, a white powder that handles well in solution—basically no visible clumping or discoloration when you reconstitute, which is good sign for the lyophilization qualiy.
The 99.9% spec isn't just a number on a sheet; it translates to cleaner and fewer off-target peaks in your LC-MS runs, but it's not suited for any in vivo work beyond initial screening given research-use-only designation.
We run a full panel before it leaves—HPLC for purity, mass spec for identity, and a residual solvent screen—and what it does is give you a COA with actual batch data, not a template, though we usually hold a retest sample for about 24 months if you ever need a recheck.
Most buyers in this space are labs needing 100mg to 5g for receptor binding or stability studies, and they'll often ask for a 1g or 5g unit, but the 10g drum is actually easier to handle if you're scaling up assays.
Packging is standerd HDPE bottles with desiccant, but let us know if you need vacuum-sealed aliquots for long-term storage—that's a common request our company can do, though it adds a day or so to lead time.
Pricing under our standard MOQ (usually 1g) works out to about £XX per mg, but check with us for the exact quote because volumes shift roughly weekly, and we always confirm stock status before shipping.
