Reference Compounds Synthesis

ISO classifies materials into two groups as reference materials (RMs) and certified reference materials (CRMs). Reference materials (reference compounds), established for measuring the quality of analysis, and are critical for any measurement process characterized by a metrologically valid procedure for one or more specified properties. Certified Reference Materials (CRMs) are used to check the quality and metrological traceability of products and to validate analytical measurement methods. For medicine industry, CRMs is the major part of regulatory specification and critical for quality assurance.

Types of reference materials (International Laboratory Accreditation Cooperation (ILAC) describes the following five types of reference material):

  • Pure substances: essentially pure chemicals, characterized for chemical purity.
  • Standard solutions and gas mixtures, often prepared gravimetrically from pure substances.
  • Matrix reference materials, characterized for the composition of specified major, minor or trace chemical constituents. Such materials may be prepared from matrices containing the components of interest or by preparing synthetic mixtures.
  • Physico-chemical reference materials, characterized for properties such as melting point, viscosity, or optical density.
  • Reference objects or artifacts, characterized for functional properties such as taste, odour, octane number, flash point and hardness.

General steps required in production of a certified reference material typically include:

  • Collection or synthesis of material
  • Sample preparation (including homogenization, stabilization, bottling etc.)
  • Homogeneity testing
  • Stability assessment
  • Value assignment (“characterization” in ISO REMCO terms).
