Switzerland was founded by Dr. B. Schircks
in 1980 to synthesize pteridines. The company
is independently owned and operated. Schircks
Laboratories has ceased production of tetrahydrobiopterin.
Biomarin has taken over the US market and
Merck Serono the European market. They will
continue to expand. They are responsible
for the supply of tetrahydrobiopterin (Sapropterin
dihydrochloride) in tablet form (Kuvan).
Over 100 other pteridines are
synthesized by Schircks Laboratories which
are mainly used in science and clinical
diagnostic applications. We are constantly
developing and improving syntheses and starting
new syntheses to meet the demands of research
and development groups worldwide.
