Description
Citric acid monohydrate is a pharmacopoeia-quality excipient with a minimum purity of 99,5 % (Ph.Eur.). Identified by CAS number 5949-29-1 and EG number 611-842-9, it has the empirical formula C₆H₈O₇·H₂O and a molar mass of 210,14 g/mol. Reported physical properties include a density of 1,54 g/cm³ and a boiling point above 170 °C. It suits chemicals in pharmacopoeia quality where reproducible weighing, buffer preparation, pH adjustment and related aqueous systems are required. The monohydrate form provides a defined water of crystallisation content for consistent preparation work. size is convenient for both development trials and routine production or laboratory use. Handle the solid organic acid according to the associated safety information and standard chemical hygiene practices in the laboratory or production environment.
