Organic Facility Information

The total GFS manufacturing capacity exceeds 100,000 liters for the combined production of inorganic and organic specialty chemicals; more than 80 years of experience are at your disposal.

We are not presently certified for cGMP manufacturing; however, we carefully follow ISO-9001:2000 guidelines and manufacture a wide range of precursor materials that facilitate the synthesis of various pharmaceutical ingredients.

General
The organic chemical manufacturing capabilities of GFS Chemicals reside in a 14,000 square foot, state-of-the-art, indoor production facility. This new facility demonstrates GFS Chemicals' long term commitment to the specialty organic chemical business, in which it has been engaged since the 1940's. GFS Chemicals has retained ISO 9001:2000 certification since 1997. Reaction temperature handling from –60o to 140oC, and pressure from full vacuum to 150 psi.

Types of Chemistry Performed
Liquid ammonia/alkali metal chemistry for the production of alkynes (acetylenes) and olefins; Halogenation/Dehydrohalogenation; Grignard chemistry; Alkylation; Amination; Bromination, Chlorination, Birch reductions, Esterification; Epoxidation; Skraup quinoline syntheses; Low pressure hydrogenation; other.

Batch Unit Operations performed
Include batch reactions; non-reactive mixing; extraction; filtration; centrifugation; crystallization and drying (tray and rotary vacuum); Distillation and stripping; sublimation (kilo lab scale).

Bulk Chemicals Routinely handled
Include anhydrous liquid ammonia; destabilized acetylene; sodium/lithium and corresponding amides; bromine; iodine; ethylene oxide; thionyl chloride; sulfuryl chloride; chlorosulfonic acid; hydrogen sulfide; sodium cyanide; liquid nitrogen; carbon disulfide trimethylchlorosilane and other organosilanes.

Core Product Base
Acetylenics, olefins, silanes, bipyridines, phenanthrolines, other heteroaromatic ligands, Grignards.

Equipment List
Kilo lab: Glassware up to 50LT. Processing is carried out in walk-in lab hoods and benchtop hoods. Distillation columns from 1” x 1' to 2.5” x 6'.

QC/Analytical Capabilities

 Includes GC (two Hewlett Packard 5890); GC/MS; FT-IR; UV-Vis; Karl Fischer; Melting point; ICP, AAGF, Ion Chromatography

Miscellaneous

Protocols are in place for handling liquified gases, refrigerants, and reactive materials such as acetylene and propargyl compounds, olefins, ethylene oxide, silanes, and most solvents including carbon disulfide. Materials currently outside of our protocols include phosgene, vinyl chloride, and polyaromatic hydrocarbons. We routinely campaign multi-ton quantities of specialty organics in glass-lined, Hastelloy C and stainless steel reactors. Smaller reactors and glassware are used to manufacture the classical GFS organics.

Product separation and purification techniques include custom- built distillation systems, as well as thin film and rotary evaporators. Various centrifuge and drying stations are equipped for the bulk handling of a wide range of organic intermediates and salts of organic acids.

Purity profiles of both raw material and finished goods are maintained through advanced analytical instrumentation that includes GCMass Spectrometry and HPLC methodologies.
