Product details
Klow is a reference-name product that appears in upstream price tables under a commercial brand designation rather than a publicly defined chemical name. As with the other reference-name preparations in the catalogue, the trade name alone is not an identity statement: the actual API composition, any peptide sequence, and CAS designation are confirmed against the batch-specific Certificate of Analysis before order placement and again at receipt. Peptuno lists Klow to support research-buyer workflows that reference these upstream codes; the per-lot COA's component-level analysis is the operative document for any downstream research or quality work.
Direct end-buyers should request explicit composition disclosure from the regulatory team before ordering rather than treating the brand name as sufficient. When a reference-name lot is released, the documentation reflects the verified composition as released, with the standard analytical scope applied to the dominant species — RP-HPLC purity, mass-spec confirmation, counter-ion, and water content by Karl Fischer. Confirm API by COA / label before use. This is reference-grade research material, distinct from compounding-scale API supply.
Regulatory note: Reference-name product without a publicly disclosed API identity; composition is confirmed on the batch-specific COA before any downstream research use. Confirm API by COA / label before use. Sold for Research Use Only under the receiving laboratory's institutional and jurisdictional regulations.
FAQ
- When does it make sense to order Klow rather than a named-API standard?
- Klow exists primarily to support buyers whose upstream procurement systems reference the commercial brand code. For most research the cleaner route is to identify the underlying API through Peptuno's regulatory-team disclosure and order the named-API standard instead, since the reference-name path adds catalog-level opacity and resolves identity only at the COA. Reserve the reference-name path for workflows that specifically require the brand designation.
- What documentation ships with a Klow lot?
- Each lot ships with a batch-specific COA covering the verified composition as released, the RP-HPLC chromatogram for the released material, mass-spec data for the dominant species, water content by Karl Fischer, and microbial limits where the application requires them. The documentation specifies the verified composition without disclosing the upstream proprietary formulation; buyers needing full composition disclosure should request it explicitly at quote stage.
- Why are fill sizes offered across a wide range for Klow?
- The 5 mg and 10 mg fills suit pilot-scale and standard aliquot work, while the 80 mg fill targets larger workflows. Fill-size choice is independent of identity confirmation, which is performed against the batch-specific COA at receipt; the underlying composition is the same across formats for a given released batch.
