screening compound for drug screens (except Targetmol brand) will have some unique characteristics of this product due to its special purpose, please check the following instructions before considering whether to order.
1. Purity:
100% of the compounds will provide quality inspection, and ensure that 100% of the molecular purity is not less than 90% (error +/- 5%), more than 95% of the molecular purity is higher than 95%. Purity and accuracy were confirmed by 1H NMR and/or LC (UV)/MS spectroscopy.
2. Spectrogram
These screening compound supplier brands (with the exception of Targetmol) only provide hydrogen or mass spectra, no more spectra. Because as long as the structure and purity are greater than 90%, they meet the conditions of preliminary screening, and you need to test yourself if you need more spectra for the article. Drug screen can be based on your needs, paid testing and provide the corresponding spectrum.
3. Information on solvents, solubility, toxicity, and instructions for use:
Most of the screening compounds (except Targetmol) are designed and synthesized by combinatorial chemistry methods, but they only meet the characteristics of drugs and have the possibility of potential patent drugs, and in fact, no experiments have been carried out. So information about solubility, solvent, toxicity or not is not available. Of course, the manual is not available. Even, some products are likely to be insoluble or very toxic.
4. Storage time:
The products for screening compounds are stored in the form of dry powder, most of which are very stable and can be stored for many years, and some compounds in our database are even stored for more than 20 years, but repeated testing is no problem. After the product is dissolved, it is recommended to store it at -20℃ for short term use, and -80℃ for long term use.
5. IP and Patents:
All products that screen compounds can be patented, but it is difficult to apply for structural protection, because the supplier is confidential about the synthesis route, and it is no problem to apply for functional patents of compounds. We are the sales company of compounds, do not require the sharing of any intellectual property rights, the customer's research results belong to the customer.
6. Documents with shipment:
Ordering screening compounds will be sent with the shipment to the QC folder, packing list.xls and packing list.sdf.
QC folder: contains all test spectra of all compounds in this order;
packing list.xls: Contains: Smiles, ID, Box, Row, Col, Mol, Vial Amount [mg]
packing list.sd: The information is the same as packing list.xls. You can also view the compound structure.
7. About the delivery time:
The delivery time of most products can be controlled within 2-3 weeks; Some special brands may take 3 or 4 weeks or so.
8. Freight:
Freight is not only referred to as international freight, different compound suppliers will also charge handling fees for each small order, which is also calculated in the freight.
9. Ordered 5mg of the product, but only 1mg came out?
All products are precisely weighed, due to the different crystal shapes of different products, or have electrostatic effects, there will be a lot of adsorption on the bottle wall and cap, for 5mg and 10mg packaging products we do not recommend you to repack. It is recommended that you add the solvent directly.
10. There is no information on solubility, so what is the recommended choice of solvent?
Under normal circumstances, we recommend to choose DMSO as the solvent, which can meet the scientific research purposes of most products, but it is also possible that other solvents have better dissolution effect, but this needs to be found through experiments.
11. No compounds in the sample bottle?
There are several possible reasons：
1. The product quantity is small, dispersed in the tube wall, difficult to observe with the naked eye;
2. The product is transparent film, which can not be seen even after centrifugation. Products are weighed, there will be no sample in the bottle, it is recommended to directly add solvent hydrolysis, according to the needs of the experiment.
