BUILT FOR RESEARCHERS

Everything you need to order with confidence

Browse the catalogue →

01

Batch documentation

Every vial carries its lot number, and Certificates of Analysis are published per lot as testing completes — never a generic document. Look any published lot up by number in the documentation library.

02

Methodology you can check

Test methods are named on the record — RP-HPLC, mass spectrometry — so your QA team can evaluate what was run, not take a percentage on faith.

03

Support that answers

Order status, documentation requests, and institutional procurement questions get a human response within one business day. Support stays within research scope — that is a feature, not a limitation.

Top research compounds

Organized by compound class. For laboratory research use only — not for human consumption.

Tested, documented, traceable

Testing results are published per lot from Certificates of Analysis issued by an independent laboratory — every purity figure on this site traces back to a document you can open and check.

Reverse-phase HPLC

Purity is assessed by reverse-phase high-performance liquid chromatography with UV detection, the reference method for peptide purity analysis. Results are reported per lot on the Certificate of Analysis issued by the independent testing laboratory.

Frequently asked questions

Ordering, documentation, shipping, and account verification.

Every catalogue entry lists its compound identity data — molecular formula, molecular weight, CAS number, and sequence where verified. Where a lot has been tested, a lot-specific Certificate of Analysis issued by an independent laboratory is published on the product page and in the COA library. Match the lot number printed on your vial label to the document.
