Analytical Chemistry

GVK BIO has cGMP & GLP compliant, state-of-the art analytical laboratory, which is USFDA, EDQM, PMDA and KFDA approved. We offer support in structure elucidation and characterisation of small molecules by spectroscopic techniques through fluorine and carbon NMR capability (using 1D, 2D NMR experiments and MS/MS experiments). We also offer cGMP compliant analytical services from pre-clinical to commercial phase III supplies in accordance with current regulatory requirements.

Analytical services are provided for variety of compounds:

Small molecules


Oligosaccharides & carbohydrates


Agrochemicals and pesticides


Drug substances & drug products


Electronic grade chemicals

Impurity Profiling

  • Isolation and characterisation of unknown impurities from starting materials, intermediates, APIs and formulations utilising the strong skills in preparative HPLC isolation and structure elucidation by NMR using coupling constants, 1D & 2D experiments like NOESY, ROESY, HOESY, HMBC, HSQC, etc., Assignment of absolute configuration by chiral derivatization agents (Mosher’s method).
  • Isolation and structure elucidation of degradants of APIs.
  • Purity determination of raw materials, intermediates and APIs by quantitative NMR (QNMR) and by HPLC assay methods using standard compounds.

Method Development & Verification Methodology

  • Method development and validation of API (in accordance with the ICH and OECD guidelines to support scale up lab) requirements and other client specifications.
  • Capable of doing short term and long term (accelerated and real time) stability studies of APIs and Intermediates and forced degradation studies.
  • Residual solvent method validation (in accordance with the ICH requirements), complete analytical services for residual solvents estimation, residual metal content and genotoxic impurities.
  • Polymorph/powder characterisation by power XRD technique.

Purification Capabilities

GVK BIO has expertise in isolation, purification and characterisation of new chemical entities and for known compounds. We also offer SFC and mass-based high throughput library purification, purity estimation of NCEs by reverse and normal phase chromatography, determination of enantiomeric excess using variety of chiral columns, high throughput purification and isolation of compounds (chiral and achiral) from milligram to kilogram scale.
