MDPI Sample Deposit Services
Samples Acceptable for Deposit
MDPI accepts all compounds, whether they are new or old, published
or unpublished (but fully characterized). Even if you have only one
chemical or biochemical compound, you can make it available worldwide
at a reasonable price by registering (free of
the samples into the MDPI database. You may be asked to deposit one
amount at MDPI as specimen. Catalysts and Enzymes are also
for deposit and distribution.
Postage for samples delivery to MDPI center in Switzerland can be paid
by MDPI. However, please contact MDPI first.
The practical handling of a compound, such as packaging, storage,
and consequently the application as well as its information
as an entry into a database, is very expensive. Therefore, all
submitted should be of high quality and characterized as fully as
with relevant physicochemical, particularly spectroscopic data.
or mass spectra should be included whenever possible. Preferably all
data should be fully presented in the corresponding publication in a
Any available GC, HPLC, flash chromatography and TLC data should be
Compounds should not be commercially readily available as
found in the Fluka or Aldrich catalogues for a normal price. However,
compounds that are in principle commercially available, but only in
small quantities, are also acceptable. Synthetic composite and
samples are also suitable for submission. At the moment restrictions
made on the collected compounds: they should be reasonably stable at
temperature, as pure as specified, not hazardous and preferably
in solid form.
The amount of each compound should be within 100mg-100g. Smaller
are also acceptable
Benefits to Sample Contributors
1. If you publish a paper in a chemistry journal, you may deposit your
compounds in the MDPI Center in Switzerland as the "supporting samples"
and standard or authentic samples.
2. Even if you have only one interesting chemical or
compound, you can quickly make it available worldwide immediately at a
reasonable price by registering (free of charge)
the compound or the enzyme into the MDPI database.
3. You may also deposit all the old compounds in the MDPI
if you do not have a place to store them.
4. All the transportation charges will be paid by MDPI.
5. Chemists help each other by contributing not only chemical
information, but also chemical substances. Then if you are an
reader of a published paper, you do not need to prepare the compounds
You may obtain the samples from MDPI quickly at a nominal cost, saving
time and money.
6. MDPI may also purchase your compound collection and pay
for delivery to MDPI center in Switzerland in cash immediately.
7. The prices of the samples distributed by MDPI may be
by the contributors. The prices should be lower than the costs required
if a user were to prepare these compounds according to the literature.
8. The remaining net profits of the MDPI sample services will
be used to fund academic activities (conferences, an MDPI prize, etc.).
Terms and Conditions of the Deposit Services
Molecular Diversity Preservation International
is a nonprofit and independent organization. Preservation of
diversity, by registration, collection, deposit and exchange of all the
available compounds, is our sole purpose. The unit amount and unit
may be published and the remaining amounts of the samples will be
and released each half year in the MDPI
database so that you know how much sample were distributed and how
much you should be rewarded. (The sample user's name and any related
information may be confidential if requested. Otherwise these are
in the database).
The submission of compounds structure and other data for publication
in MDPI database and the submission of compound samples for storage and
exchange are carried out on a fully voluntary basis on the part of the
contributor. By accepting and registering the chemical species
MDPI acquires the rights of manipulation of that amount of sample for
Contributors should obtain any necessary authority to submit the
(either in part or all of the samples). The authors accept full
for the factual accuracy of the data regarding the submitted samples.
Contributors should maintain the quality as high as possible or as
as clearly specified.
Procedure for Samples Deposit
The containers must be properly labeled by attaching the compound
abstract directly onto the container. At the very least your own
ID code should be given on the label, if the compound
abstract list is supplied together with the compounds.
Packaging and Transporting:
Avoid using too large a container for only a small amount. Primary
receptacles such as vials include those of glass or plastic. They
be fitted with a skirted stopper or a screw cap and reinforced with
tape. An outer packing of sufficient strength should be used to ensure
that the package will withstand the stresses of normal handling during
transit and will not be damaged by accidental dropping, crushing, etc.
Both the outer container and outer wrapping must bear the name and
of the sender and the recipient (MDPI). They should be labeled "research
sample". Packages should also carry the internationally recognized
green customs label, as well as any labels required by the relevant
government regulations, and should be accompanied by any documentation
required by such regulations. Carrier or freight agents and/or postal
can advise about these.
All the samples together with their Compound Abstracts
sheets or/and a disk) should be sent directly to the MDPI Center in

Sample Manipulation Procedure
The MDPI center will immediately confirm the safe arrival by e-mail,
or normal mail. Compound abstracts of the submitted compounds will be
and entered into a database by the database manager, and the samples
be stored in the archive center within 7 days. Compound abstracts will
be published in the MDPI database.
For purchased compounds, the sample contributor will receive the
within 4 weeks (Please provide detailed bank address and bank account
