Analytical Method Development

Analytical Method Development

Analytical research and development (AR&D) offers standalone services and supports our formulation development activities. The AR&D teams are integrated with preformulation, product development and quality assurance teams to ensure effective and accelerated product development. Our experience in developing methods for highly complex and unstable drug products compliments our formulation capabilities.


Method Development

We offer a wide range of compendial and non-compendial testing services. Our analytical laboratories are based on philosophy of cGLP and designed to facilitate in-house development of API as well as drug product methods like assay, dissolution, residual solvent, related substances etc.

Stability Testing

Cuckos offers GLP compliant ICH stability testing services. We have dedicated stability chambers for informal (R&D) and registration (cGMP) stability. All our walk-in stability chambers are continuously monitored. We use 21 CFR Part 11 compliant software. An alert system, back up chamber and electricity back-up assures sample integrity. The following climatic zones are available:

  • 5°C

  • 25°C/60% RH

  • 30°C/65% RH

  • 30°C/35% RH

  • 40°C/75% RH

  • Photo stability chamber

  • Customer specific conditions
