About Us

Seven Star Pharmaceutical Services is a technology-driven Contract Research Organization (CRO) that focuses on solving the drug development problems through solid state chemistry/materials science and engineering principles. We work with our clients to ensure comprehensive solutions for their needs in solid-state chemistry research, crystallization process development, and preformulation studies. Based on the molecular level understanding of materials, we guide clients in the discovery and selection of the optimal solid form for drug development using all aspects of pre-formulation studies, including API process development, regulatory support and intellectual property protection. We are flexible and deliver timely, practical, and cost-effective solutions. Our programs include salt screening, co-crystal screening, crystallization screening, polymorph screening, amorphization, scale-up crystallization, physico-chemical properties testing, particle engineering and structure elucidation of solid forms by single crystal X-ray diffraction.


We also offer routine testing on pharmaceutical solids at highly affordable pricing without compromising on its quality. We guarantee the results will be delivered in timely fashion.
We offer the following tests:
X-ray Powder Diffraction (XRPD)
Structure elucidation by Single Crystal X-ray Diffraction methods (SCXRD)
Differential Scanning Calorimetry (DSC)
Thermogravimetric analyses (TGA)
Dynamic Vapor Sorption (DVS)
Polarized Light Microscopy (PLM; including hot stage)
Karl Fischer Titration (KFT)
