white to almost white crystalline powder | [Uses]
Girard''s Reagent T is a derivatizing agent used to generate permanent cationic charge at the reducing ends of neutral oligosaccharides for easier quantification in matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS). | [Purification Methods]
It is purified by crystallisation from absolute EtOH (slight decomposition) until it has only a slight odour. Store it in well-stoppered containers because it is very hygroscopic. It is very soluble in H2O, AcOH and glycerol but slightly soluble in EtOH (0.66%). It forms water-soluble hydrazones with carbonyl compounds. [Beilstein 4 III 1133.] |
