Meropenem Specification

1. Introduction of Meropenem
Meropenem is one kind of white or almost white crystalline powder. The IUPAC name of this chemical is (4R,5S,6S)-3-[(3S,5S)-5-(Dimethylcarbamoyl)pyrrolidin-3-yl]sulfanyl-6-[(1R)-1-hydroxyethyl]-4-methyl-7-oxo-1-azabicyclo[3.2.0]hept-2-ene-2-carboxylic acid. Besides, Meropenem belongs to Active Pharmaceutical Ingredients;Antibacterial;Cnbio;pharmaceutical intermediates. In addition, Meropenem Classification Code is Anti-Bacterial Agents; Anti-Infective Agents; Drug / Therapeutic Agent; Reproductive Effect. What's more, Meropenem is soluble in 5% monobasic potassium phosphate solution, sparingly soluble in water, very slightly soluble in hydrated ethanol.

Meropenem (CAS NO.96036-03-2) was originally developed by Sumitomo Pharmaceuticals. It is marketed outside Japan by AstraZeneca with the brand names Merrem and Meronem . Other brand names include Mepem (Taiwan) , Meropen (Japan, Korea) and Neopenem (India) . It gained FDA approval in July 1996. It penetrates well into many tissues and body fluids including the cerebrospinal fluid, bile, heart valves, lung, and peritoneal fluid.
