Fluorobenzoic Acid / Fluoroaniline
Derivatives
We are actively cooperating with Shanghai Weiyuan Fine Fluorine
Chemical Co. Ltd, a well-respected and innovative Chinese producer
of these series of products. We can produce virtually any configuration
of isomer and welcome your ‘custom synthesis’ enquiries
for this and related types of aromatic fluorine molecules.
Malonyl Dichloride
At first sight, this seems to be a very basic and straightforward
product but on closer inspection, there are very few producers
who can offer a reliable quality at a realistic cost. We have
developed a source in China who can now offer regular production
of this item with consistent quality (>98% purity) and at
a price which allows its use in many synthesis reactions.
Pyridine Derivatives
This class of compound finds applications in many different fields
– from cosmetic (hair colour products), agrochemicals (pesticide
intermediates), pharmaceutical (nicotinic acids) and many many
others. We can offer the most comprehensive range of pyridine
products available anywhere, from development quantities up to
multi-tonne and beyond. Please contact us with your particular
requirements.
Tetrabutylammonium
bromide
An important phase-transfer catalyst, widely used in organic
synthesis and now available as a 99% pure solid or as a 50% aqueous
solution. Both grades can be supplied in tonnage quantities at
very competitive prices.

beta-Carotene
(Provitamin A)
Occuring naturally in many vegetables and fruits, beta-carotene
is the material which imparts the characteristic red and yellow
colouring in products like carrots, melons, peppers etc. It is
a precursor of Vitamin A and, as such, plays an important role
in disease prevention, anti-ageing and maintenance of good vision.
Our source offers various grades of material to suit many different
applications.
