EXPERIENCE
We are proud of the qualifications of Icon's staff, which gives us extensive experience and expertise in synthetics, with more than 40 years exclusively in stable isotopes. Synthetic timeframes and potential capability of synthesis quotations are based on experience which is utilized to temper references in literature.

Icon has been formed exclusively to service researcher requirements for compounds labeled with stable isotopes. Our facilities are totally dedicated to stable isotope production and synthesis. Radioisotope work is not solicited or undertaken, thus we can guarantee that materials shipped will not have been subjected to radiation exposure in synthesis or during packaging.

Quality -- Each batch of raw Isotope material is checked to ensure that it meets our rigid specifications. Synthetic work is often performed in dedicated vessels and holding cylinders to avoid even trace contamination. Each isotope product may include all or some of the following: boiling point, melting point, infra-red, mass spectroscopy, GC/MS, proton NMR, GC, TLC, HPLC, atomic absorption, and optical rotation to ensure that you are receiving a quality product. Packaging materials are often made to our own specifications to ensure ease of use and to minimize losses in handling and during transportation.

SUPPLY
Delivery -- All of our synthetic work is done in the continental USA and requirements for expedited delivery of Icon products can be handled promptly.

Non-Catalog Items -- At Icon, we welcome the opportunity to provide special quotes on any item not listed in our catalog or for specific requirements that you may have.

FLEXIBILITY
Service -- Our company is dedicated to meeting the special needs of researchers. We are willing to accommodate most special situations as they arise.

Quantity Requirements -- If less than the catalog quantity of a product is required, and the material is in stock, it is our policy to always try and meet our customers' requirements, whatever they may be, and whenever it is possible.

Special Packaging -- Icon's reputation for accommodation, quality, and service extends to meeting customized and specialty packaging requirements whenever possible.

HOW TO PLACE AN ORDER

TELEPHONE ORDERS

Because of the similarity in compounds which may be labeled in different
positions or isotopes, we require the following information:

Catalog or Quotation Number

Product Name and Labeled Position

Complete Shipping & Billing Information

Purchase Order Number

Quantity and Price

* Confirmation Purchase Orders are only required for orders in excess of $500
(Please be sure that they are clearly marked "CONFIRMATION" to avoid duplication).

FOREIGN ORDERS

Countries in which we have no representation will require a proforma invoice.
Upon payment, the order will be shipped as indicated. If you have established an
account that is current with us, the normal terms and conditions will apply.

Bromine labeled compounds are currently being used in
the life sciences, environmental and ecology studies as tracers.

Stable isotope starting materials are normally produced by separation of the naturally occuring element. Carbon monoxide is usually the choice when isolating carbon-12. The carbon-13 is reduced to 5% of its natural abundance (down to 0.05%). Commonly used in organic reaction mechanisms work and similar studies when carbon-12 can act as a "negative label."

Carbon-13 is normally produced by separation of the naturally occuring element. Carbon monoxide is usually the choice when isolating Carbon-13. Compounds are synthesized from 99atom% minimum material, however, slight dilution of enrichment may occur in multi-step synthesis and in compounds labeled in two positions when statistically each will contain 98% carbon-13. This catalog offers each compound at the highest enrichment possible. Should your research require a lesser enrichment, please request a custom quotation that we will conform to your specific needs.

Commonly used when natural abundance Carbon-13 peaks interfere with the spectrum of the material being studied. Carbon-12 solvents (depleted in Carbon-13) eliminate this problem.
