Speak to Our Experts

For more than two decades, we are providing comprehensive pharmaceutical analytical services to clients across the industry. Our services include method verification, development and validation, impurity identification and characterizations and isolation of impurities by preparative scale purification, reverse phase/normal phase, ion-exchange or gel filtration chromatographic techniques. Our analytical team works in close collaboration with our process chemistry team to ensure that every method suits the process requirements for raw materials, APIs and formulations.

Our pharmaceutical analytical services research team is well versed with current regulatory requirements to support you from early research to market.

We offer method verification, development and validation for excipients, raw materials, APIs and drug products including high potent compounds, steroids, carbohydrates and synthetic peptides.
