1. I hope to know more about Custom synthesis:

We provides custom synthesis of organic compounds for the chemical, pharmaceutical and agrochemical industries, and to universities and research institutions. We offer starting materials, intermediates, reference compounds, and derivatives of lead compounds. Compounds are made to order in scales ranging from milligrams to several kilograms. Requests for contract research services can be fulfilled. Examples of custom synthesis products are available
We employs highly experienced and accomplished synthetic organic and medicinal chemists and pharmacologists with extensive experience in industrial and academic synthesis and research. We specialize in small organic compounds, natural products, heterocycles, nucleosides, and amino acids. Our staff is capable of handling difficult synthetic assignments and providing high quality, on-time, and confidential services. We are developing an inventory of compounds that are not readily available elsewhere, and appreciate suggestions from you and your staff about products that we might offer.
The experience and supply network available to us allows us to offer chemicals for direct sale. Bulk chemicals include reagents and intermediates available in multi kilo to metric ton quantities. Fine chemicals & biochemicals include specialized compounds and compound types available in gram to kilo quantities. Price and delivery vary depending upon quantity desired and current stock availability.
We are an innovative team of qualified employees with many years of experience in the field of organic synthesis.
We offers a comprehensive product range from interesting synthetic building blocks to intermediates and reagents for research institutes, analytic laboratories, and the chemical and pharmaceutical industry.
We offer fair prices, fast delivery and high quality products.
Custom synthesis of known and unknown molecules is part of our business. We develop synthesis concepts for unknown organic chemicals and test them on the lab scale. If desired we optimize single reaction steps or complete reaction sequences on the lab scale and transfer the optimized procedures to the large scale.
We have a broad experience in the separation and purification of substance mixtures, which are difficult to purify by usual procedures, using liquid chromatography techniques (RP and NP-MPLC).
Our labs are well equipped with the necessary and modern hardware to carry out the full range of organic reactions (0.1-1000g). Analytical equipment for both identification and quality control is also available.

4. How can I get the price for a compound?
Please enquire a price preferably by writing an e-mail (info@intermediate.com.cn) or phone call at +86 10 63453699.
Please do not send orders without having a price!

-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
5. How long does it take to get a quote?
We always try to quote asap after receiving your inquiry. No longer than 48hours (working days).

-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
6. How can I order?
Orders are only accepted in writing (fax, e-mail or letter). Your order must contain the following data:
Shipping and billing address (incl. phone#, fax# and e-mail)
The name of the responsible person for order
Your PO# (if nessesary)
The product order-number, required quantity and price (if there is no price in our data base, the price according to our quotation)
Your signature

-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
7. How long does it take to get the compound?
If the material is in stock, you will get it at least after three days. If it is not in stock, you will get information about the expected delivery time.

-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
8. How can I pay?
Payment can be done by wire transfer. the bank information is given on the invoice. The invoice will be sent by Email. and fax. If original is requested, we will send by post.

-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
9. What about the purity of the compounds?
Our compounds normally have a purity of at least 95%. If a special compound has a lower purity, the information will be given in the datafield (technical grade).
Some compounds have higher purities (i.e. D-Luciferine, Coelenterazine, 5-ALA etc.) as you will see in their datafields. If there are compounds without given purities in the datafields, you will get information in the course of our quotation or order confirmation.
