Diversity Preservation International
Museum and Samples Exchange
The missions of the nonprofit
organization MDPI (www.mdpi.org)
in Switzerland are:
to preserve permanently historically
significant research chemical samples in the chmical museum in Basel, Switzerland
to share and exchange any other
rare chemical samples worldwide to make the samples readily available to
other professionals by publishing in MDPI's searchable database at the
All compounds from retired chemists,
whether new or old, synthetic or natural product, published or unpublished.
Authentic supporting samples
for papers published in chemistry journals, e.g., Molecules
Specimen from companies who
sell the chemicals in large quantities.
Samples stable at room temperature,
as pure as specified, not hazardous and preferably in solid (crystal) form.
The amounts are 10mg-100g (larger
or smaller amounts are also acceptable).
Postage will be paid by MDPI.
For further information consult
MDPI homepage (www.mdpi.org). We also would like to visit you and give
gratis lectures regarding molecular diversity assessment and preservation
in your institute (see http://www.mdpi.org/lin/talks/tour00.htm for the
abstract). Comments and suggestions are welcomed.
A part of the total amount of
certain MDPI samples can be borrowed for chemically non-destructive use
(e.g., can be recovered after solution NMR), free of charge. Authentic
crystal samples can also be borrowed for non-destructive use (X-ray, microscopic
studies, etc., where both physical and chemical properties of the sample
will not be changed) free of charge.
If the contributors agree, chemists
may obtain samples free of charge for other academic research from MDPI.
Chemists can use their own samples
to exchange for the same number of MDPI samples.
Preferably the contributor's
name and address, including e-mails, are published at the www.molmall.org
server. Direct contacts and collaboration among the samples contributors
and others are encouraged.
The total amounts of the deposited
samples are updated in the database.
Commercial use of the samples
will be possible at reasonable price. One part of the profit will be used
to reward the contributing chemists for samples distributed by MDPI and
by MDPI prize governed by MDPI
foundation (www.mdpi.org/mdpifund.htm). The rest part of profit has
been used to run several nonprofit projects (e.g., ECSOC, the e-conference
on synthetic organic chemistry at www.mdpi.org/ecsoc).
We also directly purchase high
quality samples of known structure with full characterization (MP, NMR,
etc.) and high purity.
