Some Competitive Products

COVID-19 Related

Together with partners in China, Watson develops COVID-19 IgG/IgM Rapid Test Device for the use of quick test. At the same time, Watson also scales up key intermediates of Remdesivir to satisfy the need of global customers as well as develops Poly A Na salt, K salt 26763-19-9, Pseudouridine CAS 1445-07-4 and Guanidine thiocyanate CAS 593-84-0 for the use of Covid-19 Diagnostics.

Ferene disodium salt CAS 79551-14-7

Watson has been regarded as the exclusive provider of Ferene disodium salt CAS 79551-14-7 by many world-famous Diagnostic Reagent companies. Ferene disodium salt is mainly used as colorimetric reagent for iron, which is more sensitive than other reagents (e.g. Ferrozine), molar absorptivity 35500 liters/mol cm. Watson's Ferene disodium salt is famous for its continuous high quality and its stable supply capacity.

Diethyl fluoromalonate CAS 685-88-1 & Dimethyl fluoromalonate CAS 344-14-9

Diethyl fluoromalonate CAS 685-88-1 or Dimethyl fluoromalonate CAS 344-14-9 is the key intermediate for the synthesis of fluoxastrobin. Fluoxastrobin is a leaf-systemic broad-spectrum fungicide from the chem. class of dihydro-dioxazines currently being developed for use mainly in cereal crops. The compound provides both a rapid initial effect and prolonged activity due to its protective and leaf systemic properties. Applied as a foliar spray in cereals, Fluoxastrobin provides excellent control of Septoria leaf spot, Septoria leaf and glume blotch rust, Helminthosporium diseases in wheat and barley as well as scald (Rhynchosporium secalis) and powdery mildew. Furthermore, seed and soil-borne diseases like snow mold and common bunt are also efficiently controlled, when Fluoxastrobin is used as a seed treatment. Mixtures of Fluoxastrobin with selected fungicides, such as prothioconazole often result in an increased biol. activity against these diseases. Fluoxastrobin has a favorable regulatory profile. With more energy-efficient and environment-friendly technology, we effectively avoid the toxic gas brought by the traditional route such as toluene, triethylamine and hydrofluoric acid gas, which would ensure of the stability of supply chain. Besides, our highest purity standard can reach 99% min by GC which is much higher than the unpurified 90% min product in the market. And we usually hold much in stock and can ensure of a 300MT supply each year.

Prostaglandin (Bimatoprost, Latanoprost, Travoprost, (+)-Cloprostenol isopropyl ester, etc..

Watson is one of the largest suppliers of Prostaglandin series products globally including several APIs, their intermediates, derivatives and impurities such as Bimatoprost CAS 155206-00-1, Methylamido Dihydro Noralfaprostal CAS 155206-01-2, Latanoprost CAS 130209-82-4(41639-74-1), Travoprost CAS 157283-68-6, (+)-Cloprostenol isopropyl ester CAS 157283-66-4, etc.. many of which were used (as eye drops) to control the progression of glaucoma and in the management of ocular hypertension but now are more and more used to lengthen eyelashes.

FDCA CAS 3238-40-2 & FDME CAS 4282-32-0

FDCA (2,5-Furandicarboxylic acid ) CAS 3238-40-2 and FDME (Dimethyl Furan-2,5-dicarboxylate) CAS 4282-32-0 have a large potential as a replacement for terephthalic acid, a widely used component in various polyesters, such as polyethylene terephthalate (PET) and polybutyleneterephthalate (PBT). PEF is a polymer produced from 2,5-Furandicarboxylic acid (FDCA) or Dimethyl Furan-2,5-dicarboxylate (FDME) monomers. The production of PEF allows utilization of 100% renewable resources. Avantium, a chemical technology company has recently patented a method for production bio-based PEF. Their approach utilizes six carbon sugars such as fructose, to produce furan compounds.
