Aspartame

Aspartame is a dipeptide methyl ester (phenylalanine-aspartic acid) functioning as a high-intensity, low-calorie sweetener widely used to mask bitterness in oral pharmaceutical formulations, with a phenylketonuria-related labelling requirement that makes purity control especially important. Simson Pharma's Aspartame reference standard and impurities support this exacting excipient-QC need.

Simson Pharma Global Ltd. (UK) and Simson Pharma Global LLC (USA) supply high-quality Aspartame Reference Standards, pharmacopoeial reference materials, and its related impurities to pharmaceutical manufacturers, CROs, analytical laboratories, universities, and regulatory organizations worldwide. To service the Europe and America market efficiently, Simson Pharma Limited has set up Simson Pharma Global Ltd. in United Kingdom and Simson Pharma Global LLC in USA respectively.
