CONTRACT MANUFACTURING & CDMO DIVISION

CUSTOM CHEMICAL & PEPTIDE INDUSTRIAL SYNTHESIS

At Sparta Laboratories, our Contract Development & Manufacturing (CDMO) division designs and executes multi-step chemical synthesis and custom peptide assembly for non-cataloged molecules—scaling seamlessly from analytical gram quantities to multi-kilogram commercial batches with full pharmacopeial traceability.

Process R&D & Route Design

Synthetic route scouting, chiral resolution, and stoichiometric process optimization to maximize yield and minimize related impurities.

Automated SPPS & LPPS

Automated Solid-Phase Peptide Synthesis (Fmoc/tBu) for complex sequences and Liquid-Phase Synthesis (LPPS) for small-molecule APIs.

Pilot-to-Bulk Scaling

Controlled scale-up from milligram reference standards to multi-kilogram production lots at ≥ 99.8% purity verified by UHPLC-MS & NMR.

NDA & Analytical Monograph

Strict intellectual property protection under mutual NDA. Full CoA dossier including ICH Q3A/B impurity profiles, ICP-MS metals, and LAL endotoxins.
