Welcome to our 2016 supplement, updating our pharmaceutical impurities and primary reference standards catalogue which we released in early 2015. With this update, we provide more than 1,100 new reference standards for impurity and active pharmaceutical ingredient (API) testing to the global pharmaceutical quality control community. Our impurities range under the MM brand features close to 4,000 reference standards for impurity and APIs, suitable for almost any application in analytical research and development, method validation and routine quality control. Our range of primary reference standards covers now more than 100 substances. With each product you will get an extensive certificate of analysis fulfilling ICH’s, FDA’s and other regulatory body requirements for primary standards in pharmaceutical quality control. We produce our primary reference standards under ISO Guide 34, the highest possible quality regimen worldwide, to which we are accredited.
Also, we would like to take the opportunity to inform you about some exciting news about our production facilities in Luckenwalde, Germany: • We will open a state-of-the-art warehouse in early autumn which will serve as the main hub for our global logistics operations • During our quality audit in January 2016, we have renewed our GMP confirmation • We have further improved our synthesis capacities for you to obtain more relevant substances in shorter time and to characterise them as important reference standards for pharmaceutical QC For further information, also on how to best use our reference standards, we would like to point you to the introduction of our 2015 catalogue version. You don’t find what you are looking for? Please contact the local LGC office close to you, all contacts are on the back of this catalogue.
