Single-molecule and enriched fractions
From extract to molecule.
Compound isolation, structural characterisation, and analytical method development for clients pursuing single-molecule or enriched-fraction products. Positioned alongside contract research organisations as a complementary upstream partner.

MATRIX
01 · Analytical techniques
The working techniques.
Isolation and characterisation work is run through the partner laboratory matrix — ISO 17025 accredited facilities in the EU and US. Motark, via our manufacturing partners, will coordinate the programme; the analytical work is performed at the partner accredited for the method.
Preparative HPLC
Reversed-phase and normal-phase preparative chromatography for milligram-to-gram isolation of single compounds against an analytical reference.
LC-MS confirmation
Mass-spectral identity confirmation against reference standards or de novo structural attribution at the partner laboratory matrix.
NMR characterisation
¹H, ¹³C, and 2D NMR characterisation through partner academic and contract laboratories for unambiguous structural attribution.
Enriched fractions
Where single-molecule isolation is not the brief, standardised enriched fractions with marker ratios and residual-profile characterisation.
02 · Positioning
Upstream of the CRO.
Three positioning points that determine whether Motark is the right isolation partner for a programme.
01
Upstream of the CRO, not in competition with it
Motark supplies the standardised starting material with chemotype characterised against a reference standard. The Contract Research Organisation (CRO) performs the clinical or preclinical work on that material. The relationship is complementary.
02
Single-molecule and enriched fractions, separately scoped
Single-molecule isolation engagements are scoped against milligram-to-gram deliverables with full structural characterisation. Enriched-fraction engagements are scoped against marker ratios and run on the standard commercial-supply timeline.
03
Method handed over to the client
Where a method is developed for a client programme — HPLC marker, LC-MS confirmation, or stability protocol — the validated method is transferred to the client at programme handover. The client owns the method going forward.
