Specialty Chemicals and Pharma Intermediates
Performance of Specialty Chemicals
Specialty Chemicals used to manufacture other products like adhesives, construction chemicals, elastomers, polymers, agrichemicals, lubricants,
etc.
Performance of Pharma Intermediates
Pharma Intermediates are prepared based on Chloromethyl Isopropyl Carbonate (CMIC) and
Hexamethyldisilazane (HMDS).
Chemcon Speciality Chemicals Pvt. Ltd. is one of the global leading specialty firms that produce a range of specialty
chemicals: pharma intermediates. Amongst which, HMDS and CMIC are important products provided by Chemcon.
Applications and Uses - Hexamethyl Disilazane (HMDS)
Used as an excellent adhesive promoter.
Widely used in the paints and coatings industry.
Used instead of the critical point drying in Electron Microscopy.
Used in the semiconductor industry due to its ability to supplement the adhesion of photoresist on silicon surfaces.
Used as an excellent agent in silylation of alcohols, phenols, amines, and acids.
Used as a lubricant, coupling agent, deactivator for chromatographic support materials, chemical intermediate, etc.
Chloromethyl Isopropyl Carbonate (CMIC)
The rising importance of CMIC in the field of medicine is due to its 99% clarity assurance and its use to prepare tenofovir.
Tenofovir disoproxil hemifumarate salt is basically prepared using dealkylating (R)-9-[2-(Diethyl phosphonomethoxy)
propyl) adenine.
Properties of CMIC
It has a purity of approximately 98%,
Its density ranges from 1.1390 to 1.1430
It is easily soluble in chloroform.
Its 147.5 °C at 760 mmHg and its flash point is 50 degree Celsius.
