Three Pillars of Competitive Advantage

PhloSyn's proprietary technology stack integrates hardware innovation, full-stack automation, and AI-driven intelligence — enabling a new paradigm for molecular synthesis and manufacturing.

01
HSCF Technology

High-Speed Circulation Flow Reactor

A breakthrough reactor platform capable of stably handling solid-participating, heterogeneous, and highly exothermic reaction systems — overcoming the fundamental limitations of conventional flow chemistry. With exceptional mass and heat transfer efficiency, the HSCF enables clog-free continuous operation and seamless scale-up from milligram to kilogram scale, dramatically reducing process development timelines. Core patents granted, covering 30+ mainstream reaction types.

Key Capabilities— hover to explore

Solid-Phase Reactions

The HSCF reactor uniquely handles solid reagents and catalysts in continuous flow — a challenge that defeats conventional flow systems. Proprietary internal geometry prevents clogging even with high solid loadings, enabling reactions like Grignard, Suzuki with heterogeneous catalysts, and slurry-phase transformations.

Heterogeneous Systems

Immiscible liquid–liquid and gas–liquid–solid triphasic reactions are handled with precision. The reactor's high-shear mixing zone creates stable emulsions and maximises interfacial contact area, dramatically accelerating mass transfer rates compared to batch or standard flow reactors.

mg-to-kg Scale-Up

Seamless linear scale-up from milligram discovery quantities to kilogram production batches without re-optimisation. The identical flow regime at every scale means process parameters transfer directly, compressing typical scale-up timelines from months to days.

30+ Reaction Types

Patent portfolio covers over 30 mainstream reaction classes including nitration, diazotisation, lithiation, hydrogenation, ozonolysis, and photochemistry. Each reaction type has been validated with real pharmaceutical intermediates, providing a ready-to-deploy toolkit for drug synthesis campaigns.

PhloSyn's three-pillar technology stack works in concert — HSCF hardware enables reactions previously impossible in flow, the automation platform orchestrates end-to-end synthesis, and AI optimization continuously improves process efficiency.

02
End-to-End Manufacturing

Universal Automated Multistep Synthesis Platform

A proprietary fully automated, integrated universal flow synthesis platform enabling true end-to-end molecular manufacturing. The system incorporates highly integrated post-processing units including liquid separation, rotary evaporation, filtration, drying, and recrystallization. It supports direct transfer and rapid reproduction of literature reaction conditions for semi-continuous synthesis, backed by a complete automated hardware and software control system.

Key Capabilities— hover to explore

Automated Synthesis

Fully autonomous execution of multi-step synthetic sequences without human intervention between steps. The software orchestration layer schedules reagent additions, monitors reaction progress via inline analytics, and triggers the next step only when conversion criteria are met — eliminating operator variability.

Post-Processing Integration

Inline workup modules — liquid–liquid extraction, rotary evaporation, filtration, drying, and recrystallisation — are seamlessly chained after each reaction step. This eliminates manual transfer losses and reduces cycle time by up to 60% compared to traditional batch workup procedures.

Semi-Continuous Production

Literature procedures can be directly imported and reproduced within hours. The platform's condition-transfer engine maps batch parameters to flow equivalents automatically, enabling rapid feasibility assessment and fast entry into GMP-ready semi-continuous manufacturing.

Button-push On-demand Synthesis

Operators initiate complex multi-step syntheses with a single command. The platform manages all hardware interlocks, safety checks, and process sequencing autonomously. This democratises access to advanced synthesis — enabling non-specialist teams to run complex chemistry reliably.

03
Data-Driven Process Intelligence

AI + High-Throughput Reaction Optimization

A high-success-rate reaction optimization system powered by real experimental data, designed to significantly improve R&D success rates. By combining AI-driven modeling with High-Throughput Experimentation (HTE) technology, the platform enables smarter and faster process development. Optimization results transfer seamlessly to the HSCF platform for scale-up and production, eliminating translation barriers. The system forms a closed "Data–Model–Experiment" iteration loop, continuously accumulating proprietary process assets.

Key Capabilities— hover to explore

AI-Driven Optimization

A Bayesian optimisation engine trained on PhloSyn's proprietary experimental database recommends the next experiment to run, maximising information gain per experiment. The model incorporates mechanistic priors and molecular descriptors, achieving optimal conditions in 5–15 experiments versus 50–200 in traditional DoE approaches.

HTE Integration

High-Throughput Experimentation (HTE) arrays run up to 96 parallel micro-scale reactions simultaneously. Automated liquid handling, inline UV/Vis and LCMS analysis, and direct data ingestion into the AI model create a tight feedback loop that compresses weeks of optimisation into 24–48 hours.

Seamless HSCF Transfer

Optimised conditions from HTE micro-scale experiments are automatically translated into HSCF flow parameters via a physics-informed transfer model. This eliminates the traditional 'valley of death' between discovery-scale optimisation and production-scale flow synthesis.

Closed-Loop Iteration

The platform continuously learns from every experiment run across all projects, building a compounding proprietary dataset. Each new synthesis campaign benefits from accumulated process knowledge — improving first-pass success rates over time and creating a durable, defensible competitive moat.
