Specialty Chemicals

Welcome to Spectra Group Limited, Inc., a custom synthesis and contract R&D company with hands-on experience and expertise in organic and physical organic chemistry. SGL maintains a fully modern facility with instrumentation capabilities which allow us to perform R&D synthesis as well as large scale manufacturing.

To ensure the purity of our products, we analyze them using sophisticated instrumentation such as GC/MS, NMR, HPLC, IR, UV-Vis and elemental analysis and can also provide these services to our customers. As a specialized contract research & development company, we are uniquely positioned to provide organic compounds and precursors to pharmaceuticals and universities as well as large research organizations.


Spectra Group is your source for fine chemicals.

New Catalog 6-21-10 Now you can download our entire catalog in one concise file and search by CAS#, catalog number, chemical structure or chemical name to find your desired product. We are adding compounds frequently, so be sure to check back every so often. To search by chemical category, you may download the individual files below for a given category of compounds. Please be aware that the files below are not as current as the main catalog and they should only be used for categorical searches until we update those files as well.


Acetylenes -- for use as precursors in organic synthesis

Adamantanes

Anthracenes -- Functionalized anthracenes and anthraquinones

Aromatic Amines -- substituted aryl amines

Aromatic Hydroxyketones

Aryl Iodides -- Most of these iodides have multiple functionalities and are perfect precursors for organic chemists starting a multistep synthesis. Please check other categories for more specialized iodides.

Aryl Iodides w/Carbonyl Substituents -- aryl iodides prepared with aldehyde substituents. These molecules with multiple functionalities are attractive precursors for all synthetic chemists.

Aryl Nitriles -- aryl nitriles and benzyl nitriles.

Benzothiophene and Isothiazoles -- this group includes several substituted aryl halides.

ß-Keto Carbonyls -- a wide variety of ß-keto carbonyls. In addition, several molecules in this category contain a cyano group between the two carbonyls.

Borates -- includes triphenylbutyl and tetraphenyl borates derivatized with various chromophores and polymerizable groups, etc. They can be used as coinitiators for Norrish Type II photoinitiators in place of amine synergists as a way to improve polymerization rates.

Cyclopropeniums -- can be used as cationic thermal initiators.

2,3-Dimethylbenzenes -- includes 1,4-dibromo-2,3-dimethylbenzene.

Dioxolanes -- masked carbonyls are the perfect precursor for multistep synthesis.

Glyoxylates & Oxalates

Indoles & Miscellaneous Aromatic Compounds

Iodoanisoles & Iodophenols -- a wide variety of iodinated phenols and anisoles

Leucodyes -- an extensive array of leucodyes including leucobases and leuconitriles of crystal violet, malachite green, basic fuchsin, victoria pure blue, rhodamine 6G, and many others. These dye precursors are useful in various areas of photoscience, including color-on-demand formation.

Oxadiazoles

Pyrazoles & Tetrazoles

Xanthene & Fluorone Dyes -- a number of specialty xanthene/fluorone dyes as well as xanthone precursors. Includes some of Spectra Group's line of visible light photoinitiators -- H-Nu 470, H-Nu 535, and H-Nu 635.
