Consultant for Etomidate Freebase Synthesis

We are seeking an experienced organic chemist, medicinal chemist, pharmaceutical process-development chemist, or pharmaceutical research consultant with relevant experience in API/process chemistry and preferably familiarity with Etomidate Freebase (CAS 33125-97-2) or closely related pharmaceutical synthesis and process-development work. Project Objective Our team will perform the laboratory work locally in the Philippines. We are looking for an external technical consultant who can recommend the most practical process approach and guide our team through route selection, process development, analytical considerations, troubleshooting, optimisation, and technical documentation. The intended application is R&D, technical training, process development, and knowledge transfer. The target is approximately 200 g of isolated R-(+)-Etomidate freebase, subject to final technical review, laboratory capability, regulatory requirements, and agreed specifications. Scope of Technical Support The selected consultant should be able to support: KSM / starting-material and route selection Evaluation and comparison of practical synthetic routes Process-development and optimisation recommendations Raw-material, reagent, solvent, and consumables planning Laboratory-equipment requirements Analytical strategy and purity / impurity considerations Process monitoring and interpretation of laboratory results Troubleshooting during execution Scale-up considerations relevant to the proposed laboratory scale Laboratory handling and storage considerations Knowledge transfer and technical training Final technical / process documentation Our team will conduct the laboratory execution. The consultant's role is to provide technical direction, documentation, review, troubleshooting, and process-development guidance throughout the agreed scope. Current Laboratory Equipment We currently have access to: Fume hood Standard borosilicate glassware and round-bottom flasks Magnetic stirrer / hot plate and heating mantle Thermometer / temperature probe Ice bath / basic cooling setup Reflux condenser Separatory funnel Vacuum filtration / Büchner setup Analytical balance pH paper Drying oven If additional standard and readily available laboratory equipment is required, please identify it in your proposal. We may be able to procure additional equipment quickly if it is reasonably priced and readily available locally. Preference will be given to process approaches that can be executed mainly with standard organic-chemistry laboratory equipment and that minimize the need for highly specialized or difficult-to-source equipment. What We Want to See in Your Proposal Please provide sufficient technical detail for us to properly evaluate and compare your proposed approach before selecting a consultant. The complete proposed SOP / process procedure must be included as part of your proposal so that our team can review the route, required materials, equipment, process practicality, and overall feasibility before selecting a consultant. Your proposal should include: Your recommended KSM / starting-material strategy The route or route options you consider most practical Approximate number of process stages Comparison of the proposed route with alternative routes you would consider Why your preferred approach is suitable for approximately 200 g scale Complete list of required raw materials, KSMs, reagents, solvents, consumables, and critical materials Equipment required beyond what we already have Analytical/testing requirements Expected major technical challenges or risk points Your proposed process-development and optimisation strategy The complete proposed SOP / process procedure for your recommended route Process controls, monitoring requirements, and important decision points that our team should follow How you would guide our team during laboratory execution How troubleshooting and process adjustments would be handled What support you would provide if the initial execution requires optimisation or adjustment Proposed milestones, timeline, and commercial terms The complete SOP is an important part of our proposal evaluation. We want to review the proposed process before choosing a consultant so that we can compare the practicality, complexity, equipment requirements, material availability, development risk, and overall suitability of each candidate's approach. Applicants who provide only a general description of the route without sufficient process documentation may not provide enough information for us to properly evaluate the proposal. We would also like to understand what additional documentation you can provide as part of the engagement, including the final process/SOP package, analytical information, observations, troubleshooting guidance, optimisation recommendations, and technical-transfer documentation. After reviewing the proposals and confirming the preferred route and procedure, we will select the consultant and proceed with the agreed project scope and technical guidance. Preferred Route Characteristics Our priorities are: Simple and practical execution Minimum number of difficult process steps Readily available KSMs and raw materials Reasonable development and manufacturing cost Low practical risk of batch failure Minimal reliance on specialized equipment Suitable for technical training and future process transfer Reproducible and well documented Candidate Background Preference will be given to candidates with demonstrated experience in: Organic synthesis Pharmaceutical process chemistry Medicinal chemistry API process development CMC / pharmaceutical development Analytical characterization Impurity and purity assessment Process scale-up Technology transfer CRO/CDMO or pharmaceutical manufacturing environments Please briefly describe relevant projects you have completed and the level of hands-on involvement you had in route development, optimisation, scale-up, troubleshooting, and technology transfer.
