The Fields That Matter
- Product identity: name, sequence, and batch number must match your order.
- Method: purity is meaningless without stating the analytical method (typically HPLC).
- Results: compare measured purity against the stated specification.
- Date and signature: verify the document is current and authorized.
Red Flags
Generic, unverified claims such as blanket certifications without batch data warrant caution. Always request batch-specific documentation for research-critical applications.
