What class of compound is TAK-653?

TAK-653 is classified as an AMPA receptor positive allosteric modulator (also called an AMPA receptor potentiator). In in-vitro receptor and cell-based assays it is described as binding an allosteric site on AMPA-type glutamate receptors and increasing glutamate-evoked receptor responses, with minimal agonistic activity when glutamate is absent. Modern Aminos supplies TAK-653 solely as a reference compound for this kind of in-vitro laboratory work.

How TAK-653 is tested

  • Independent HPLC testing: Every TAK-653 batch is tested by an independent third-party laboratory before release, and multiple vials from each batch are tested.
  • Latest published result: Lot TA2601A (bulk material), Vanguard Laboratory, reported March 31, 2026: 99.25% chromatographic purity by HPLC-UV/VIS. View COA (PDF)
  • COA on every vial: Each vial label carries a lot number and a QR code that opens the certificate of analysis for that vial’s batch. You can also look up any lot at COA Batch Search.
  • How we test: See our Quality Assurance Program and why HPLC testing matters.
  • Same-day shipping: US orders placed before 4 PM CT, Monday–Friday, ship the same business day via FedEx or UPS. TAK-653 ships within the United States only.

TAK-653 FAQ

What is TAK-653?

TAK-653, also called osavampator or NBI-1065845 (CAS 1358751-06-0), is a small-molecule research compound with the formula C19H23N3O3S and a molecular weight of 373.5 g/mol. It is classified as an AMPA receptor positive allosteric modulator and is sold by Modern Aminos for laboratory research use only.

What are the other names and identifiers for TAK-653?

TAK-653 is also known as osavampator (its INN) and NBI-1065845, and is often written as TAK 653 or TAK653. Its CAS number is 1358751-06-0, its PubChem CID is 56655833, and its InChIKey is PXJBHEHFVQVDDS-UHFFFAOYSA-N.

What class of compound is TAK-653?

TAK-653 is an AMPA receptor positive allosteric modulator, also described as an AMPA receptor potentiator. In in-vitro assays it increases glutamate-evoked AMPA receptor responses while showing minimal agonistic activity on its own.

Is TAK-653 a peptide?

No. TAK-653 is a small molecule (a pyrazinothiadiazine dioxide derivative, C19H23N3O3S), not a peptide. It is sometimes grouped with research peptides because peptide suppliers also carry it.

How is TAK-653 purity verified?

Every TAK-653 batch is tested by an independent third-party laboratory using HPLC before release. The most recent published bulk-material COA (lot TA2601A, Vanguard Laboratory, reported March 31, 2026) shows 99.25% chromatographic purity.

How do I read the TAK-653 certificate of analysis?

Match the lot number on your vial label to the lot number on the COA. Then check the compound name, the testing laboratory, the report date, the method (HPLC-UV/VIS), and the result, which is chromatographic purity for bulk material or measured concentration for finished vials. Scanning the vial’s QR code opens the matching COA.

Where can I buy TAK-653 online?

You can buy TAK-653 for research directly from this page at Modern Aminos, a US supplier. It is sold only to qualified researchers and institutions for laboratory use, and wholesale pricing is available through the Modern Aminos wholesale program.

How does TAK-653 ship and how should it be stored?
