Thanks to the skills of the founder and to a mandate of representation conferred by one of the most important phenol and acetone producers, Agechim, a small family-run business, established itself on the national market by managing significant quantities of phenol, acetophenone, alfamethylstyrene and acetone. At the beginning of the 1980s, his son Stefano joined the company and enthusiastically started the expansion of the products marketed, in particular monomers, acrylates, methacrylates and other specialties such as bisphenol, PTBF and organic peroxides are developed. At the same time, relations with the most important national and international manufacturers are increasing and consolidating and Agechim is thus able to offer its customers not only high quality products that are always up-to-date and respectful of the laws in force, but can guarantee regular supplies and technical support.

Pharmaline is a company active and present in the pharmaceutical market for more than 25 years, supplying a large variety of fine chemicals to its customers. The company was created in 1990 by Luciano Sorresini who, after many years in the chemical sector, decided to pursue his own path. Thus began his activity as an agent of Tradeco, selling more and more chemicals in the pharmaceutical market. During these years, Pharmaline constantly increased its representatives for the Italian market. Its strong presence in the field of organic intermediates for chemical and chemical-pharmaceutical synthesis has given the company the opportunity to work with fine chemical manufacturing companies located in Japan, India, China and the UK. Subsequently, Pharmaline began to cooperate with distribution companies present in numerous states and became the Italian member of the INDIS Group. In 2011 the company was acquired by Ilario Ormezzano and merged into the commercial offices in Via Ripamonti 44. Currently the Pharmaline division specializes in fine chemicals.
