Formulation reverse engineering is the analytical process of deconstructing an existing product to identify its composition, ingredient proportions, and preparation methods. By utilizing advanced analytical chemistry to deconstruct a Reference Listed Drug (RLD), we peel back the layers of complex formulations to reveal the exact identity and concentration of every ingredient. This process is the cornerstone of modern pharmaceutical development, enabling researchers to decode the sophisticated interplay between active ingredients and functional excipients.
Whether aiming for bio-equivalence in generics or optimizing next-generation drug delivery systems, understanding the RLD's internal architecture is essential for reducing development risks and ensuring product performance. At BOC Sciences, we specialize in the comprehensive deconstruction of a wide range of dosage forms, from conventional oral solids to complex long-acting injectables and topical semisolids.
Our distinct capability lies in the high-fidelity quantification of non-chromophore excipients and the spatial resolution of multi-layer or composite drug products using techniques like Raman chemical imaging and TOF-SIMS. Supported by a proprietary excipient spectral library and decades of formulation experience, we serve a global client base of generics developers and specialty pharmaceutical companies. Our analytically driven insights help clients navigate formulation challenges with confidence, replacing iterative guesswork with data-driven development strategies.

Client Needs: A pharmaceutical developer required the exact quantitative composition of a high-molecular-weight polymer matrix in an RLD.
Challenges: The matrix contained overlapping grades of PEO and HPMC, making standard separation extremely difficult.
Solution: We employed a multi-detector approach using GPC-ELSD coupled with q-NMR to isolate the specific molecular weight distributions. By applying customized chemical derivatization, our team distinguished between different viscosity grades of cellulose ethers. This allowed us to precisely calculate the polymer-to-plasticizer ratio, ensuring the client could replicate the signature zero-order release kinetics of the reference product.
Outcome: The client successfully reproduced the RLD's dissolution profile using the identified excipient grades.
Client Needs: A biotech firm needed to identify the precise lipid-to-cholesterol ratios in a complex injectable liposome.
Challenges: The extremely low concentration of pegylated lipids required high-sensitivity detection without matrix interference.
Solutions: Our laboratory utilized High-Sensitivity LC-MS/MS and DLS to characterize the lipid bilayer. We performed high-resolution quantification of phospholipids and cholesterol while determining the exact degree of PEGylation. Additionally, we analyzed the drug-to-lipid ratio and Zeta potential to reveal the stabilization mechanism.
