Susan Massie, Marketing Director, Greyhound Chromatography and Allied Chemicals Email: sue@greyhoundchrom.com

Susan Massie is the Marketing Director for Greyhound Chromatography and Allied Chemicals, affectionately known as 'Greyhound' in our scientific community. Greyhound was founded by Susan's husband Paul Massie almost 40 years ago, Susan hasn't been in the business for all of that time but has been involved with Greyhound for over 17 years. Greyhound continues to grow, expanding into new markets and taking on the challenges of our ever changing environment. It's heartwarming to witness the world waking up to the fact that we are damaging our planet on a daily basis. Every action we take has a direct effect on our planet and the world we leave behind for future generations. Susan is passionate about climate change and is happy to work in an industry that can have a direct effect on reducing the impact of our actions on the environment. All of the team at Greyhound take our responsibilities very seriously, the products that we supply are used by the world's leading scientists and chemists as they endeavour to monitor and repair the environment. All is not lost, if we all take responsibility for our actions, from reducing our waste and reusing or recycling our material collateral we can make a difference. The internet is full of useful advice and guidance, Susan is proud to contribute to that wealth of knowledge whenever she can.

Greyhound prides itself on personal service which provides prompt, efficient, cost-effective, safe delivery of all products. Greyhound provides technical advice and distribution of Certified Reference Standards and Materials, Laboratory Consumables, Solvents and Reagents across all scientific disciplines. Greyhound Chromatography offers over 1 Million products from its UK warehouse. The team at Greyhound are proud to support the work of the world's leading scientists and chemists as they challenge the abuse of our planet and try to make a difference to the world we leave behind for our ancestors.

TCI Click Chemistry

BROCHURE AVAILABLE HERE

Chemical Structure

“Click Chemistry” is a term which was first described by K. B. Sharpless of the Scripps Research Institute in 2001 to describe reactions that afford products in high yields and in excellent selectivities by carbon-hetero bond formation reactions. The term “Click” means joining molecular pieces as easily as clicking together the two pieces of a seat belt buckle. In general, the definition of click chemistry is described as follows:

1. give very high chemical yields of desired products

2. combination of readily available simple building blocks

3. generate almost no byproducts

4. simple product isolation by non-chromatographic methods

5. reaction proceeds in water, as well as in organic solvents

 

TCI Silane Coupling Agents

BROCHURE AVAILABLE HERE

Silane coupling agents are organosilicone compounds having two functional groups with different reactivity. One of the two functional groups reacts with organic materials and the other reacts with inorganic materials. Their general structure is as follows:Chemical Structure Image

Where Y denotes a functional group that links with organic materials, e.g. vinyl, epoxy, amino group and so on. X is a functional group that undergoes hydrolysis by water or moisture to form silanol. This silanol links with inorganic materials. Representative examples of X include chlorine, alkoxy, and acetoxy group.

Silane coupling agents are effective for the improved adhesion at the interface between the organic and inorganic materials and have been frequently utilized to enhance the strength and improve the performance of glass-fiber reinforced plastics. Recently, they have been used in the manufacture of inorganic-organic hybrid materials such as the laminating board for printed circuit boards, artificial marble, plastic magnets, and silica-immobilized bioactive compounds.

In addition to the original purpose of improving the adhesiveness of an interface, different applications are being explored. Examples include synthesis of moisture crosslinkable polymers using the reactivity of hydrolytic functional group, to give antistatic and antibacterial properties from surface treatment using silane coupling agents. It is expected that silane coupling agents will be applied in many fields.
