For Contract Research Organisations
CROs run studies on behalf of sponsors who will audit the paper trail. Lyochem supplies lot-traceable reference material with a per-lot data packet harmonized across multi-site shipments, an IND-aware reporting structure on scale-up, and reservation against shifting sponsor timelines.
The situation
A CRO's reference material is only as good as its documentation under audit. When a sponsor's QA reviews the study, the standard's identity, purity, and lot history have to reconcile across every site that ran the assay — a mismatch between sites is a finding.
Lyochem harmonizes the per-lot packet across multi-site shipments so the same study references the same documented material everywhere, and structures reporting to be legible to a sponsor's IND-aware review on scale-up campaigns.

How procurement runs
Tell us the sponsor's documentation expectations and the sites involved; we confirm the available records and agree any additional reporting requirements.
Multi-site shipments carry a harmonized per-lot packet so every site references identical documentation.
Lot-traceable reporting structured for sponsor review, IND-aware on scale-up campaigns.
Forecast-based reservation absorbs sponsor-timeline shifts across the campaign.
The release packet
The analytical packet — not the price — is what an audit, a reviewer, or a downstream SOP actually checks. Request the sample data packet to vet the depth before a PO.

Methods and results listed on the matching batch COA; extra identity or sequence work by prior agreement

Before a first order
Ask sales for the COA matched to the offered or supplied lot. It records the tests actually completed, their specifications, and results. Tell us the sponsor's required methods and document set before quotation so capability, timing, and any additional cost can be agreed.
Multi-site shipments carry a harmonized per-lot packet so every site references identical documentation for the same study. This avoids the cross-site mismatches that turn into audit findings.
Impurity profiling and quantitative amino-acid analysis are available on request alongside the standard identity/purity packet — useful when a method or a sponsor requires content assignment beyond HPLC area-percent. Our lab notes on impurity profiling and AAA describe what each adds.
Yes — forecast-based reservation holds against an expected window so a sponsor-driven schedule change does not reset your lead time. Discuss the campaign forecast at quote stage.
