A CRO sourced matched standards and reconstitution ancillaries together for a multi-site metabolic campaign
A contract research organisation running a multi-site metabolic-pharmacology campaign needed not just harmonised reference standards but matched reconstitution diluents across every site, so that handling variability did not creep into the cross-site data. A single bundled supply line closed both halves of the problem.

Challenge
The CRO's Project Manager was provisioning a sponsor-driven metabolic-pharmacology campaign across several sites in three regions. The reference-standard harmonisation problem was familiar — a single locked synthesis route with equivalent per-lot packets — but a second, subtler problem had bitten a previous campaign: sites had reconstituted the same lyophilized standard with different diluents (some bacteriostatic water, some plain sterile water, one site improvising acidic water for a poorly-soluble member), and sponsor QA flagged the resulting handling variability as a possible source of cross-site inconsistency. The Project Manager needed a supplier that could lock the standards to one route AND supply matched reconstitution ancillaries — the same diluents, in the same forms, to every site — so that reconstitution was a controlled step rather than a per-site improvisation.
Approach
Lyochem scoped the campaign as a bundled supply line: the reference standards released against a forecast-reserved single synthesis route with harmonised per-lot data packets, plus a matched ancillary kit shipped to every site — bacteriostatic water for the multi-use stocks, sterile water for the single-use and benzyl-alcohol-sensitive readouts, and dilute acetic-acid water for the one aggregation-prone member that resisted neutral-pH dissolution. The reconstitution approach was documented per standard so each site followed the same diluent-to-molecule mapping, and the ancillaries shipped with their own research-use handling notes. Where multiple standard batches were needed, each carried a lot-to-lot bridging overlay so the standard side of the audit trail stayed continuous.
Outcome
Elapsed time from RFQ to first coordinated site shipment was a few weeks. With both the standards and the reconstitution diluents matched across sites, sponsor QA accepted the harmonised package — standards plus documented diluent mapping — without raising handling-variability questions on the cross-site merge. The CRO has continued sourcing the standard-plus-ancillary bundle against a rolling forecast for the follow-on campaign, treating reconstitution as part of the controlled supply rather than a site-level variable.
“We had solved standard harmonisation before, but the diluent was the gap that quietly cost us a clean merge last time — six sites reconstituting the same powder three different ways. Getting the standards and the matched diluents from one supply line, with the diluent-to-molecule mapping documented, was what made reconstitution a controlled step instead of a confound.”
