This week we added two product pages to the catalogue: GHK-Cu (Copper Tripeptide-1, CAS 89030-95-5) and Acetyl Hexapeptide-8 (INCI Acetyl Hexapeptide-8, CAS 616204-22-9). Each page opens with a 15-item identifier block instead of a marketing paragraph, so a buyer can check the registry number, sequence, molecular formula and molecular weight before writing to us. One condition applies: the block contains objective identifiers only, and every commercial value is agreed per order and stated on the batch COA.
Which identifiers are published?
For GHK-Cu the block lists CAS 89030-95-5, the Gly-His-Lys sequence complexed with Cu2+, C14H21CuN6O4, molecular weight 400.91 and EINECS 1308068-626-2. For Acetyl Hexapeptide-8 it lists CAS 616204-22-9, C34H60N14O12S, molecular weight 889 and EINECS 1592732-453-0. Physical form, appearance and storage guidance are included as catalogue information, not as release limits.
Why did we leave the result fields empty?
Because a result without its method is not comparable. Our COA section now lists field names only: appearance, identity, assay, water, residual solvents, heavy metals and microbial limits. The actual results, limits and methods belong on the signed batch COA for the order. Consider two suppliers reporting 100 g of a powder where one quotes a value on an as-supplied basis and the other on a dried basis: without the basis stated, the two numbers differ by the water content, yet both are internally consistent. We would rather publish no number than one that cannot be checked.
What can a buyer request this week?
A sample, the current COA, MSDS, TDS and the analytical reports relevant to the destination market. Tell us the intended format and the documents your QA team needs, and we will list them in the quotation.
What did we not publish?
No purity figure, no fixed shelf life, no minimum order, no certificate badge and no stock or lead-time claim. Those are specific to a supplier's own capability and are confirmed in the quotation rather than asserted in a catalogue.
How do these pages connect to the rest of the site?
Both pages link to the technical reading cluster and to the related products in the same application family, so a buyer can move from an identifier to the method question behind it without leaving the site.
