Why batch-level testing matters
Purity is a property of a specific synthesis batch, not of a compound in general. Research applications require high purity — commonly at least 98% — so that observed effects can be attributed to the intended molecule rather than to deletion sequences, oxidised variants, or residual solvents. Certificates issued by a laboratory with no financial relationship to the supplier are the standard for that verification.
