Reference

Endpoint:

water solubility

Type of information:

experimental study

Adequacy of study:

key study

Study period:

10 August 2015

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

study well documented, meets generally accepted scientific principles, acceptable for assessment

Qualifier:

no guideline followed

Principles of method if other than guideline:

The analytical method is 1H Nuclear Magnetic Resonance (NMR) Spectroscopy: A dissolved sample is treated
with RF pulses in a strong, homogeneous magnetic field. At their resonance frequency the atom nuclei with
magnetic properties absorb RF energy and release it afterwards, generating a detectable NMR spectrum.
The nuclei (e.g. the protons, present at the different sites of organic molecules) provide a spectrum
containing information about
* the chemical surroundings of the nuclei at their individual shifted resonance frequencies /ppm
= "chemical shift"
* the stoichiometric relations (integrals I) between these different sites
* the number of nuclei of other sites which can interact via through-bond-coupling.
NMR Spectroscopy allows the analysis of complex mixtures in the sample.
