L-(+)-Alaninol ((S)-(+)-2-Amino-1-propanol) is a chiral amino alcohol used as a building block in pharmaceutical synthesis, notably as a key chiral intermediate in the production of the antibacterial levofloxacin, a precursor to chiral auxiliaries and ligands for asymmetric synthesis, and a key intermediate in the production of agrochemicals and specialty chemicals. It appears as a hygroscopic, colorless to slightly yellow liquid with a mild amine odor. This chemical has a CAS number of 2749-11-3, a molecular formula of C3H9NO, and a molecular weight of 75.11. It should be stored at ambient conditions, but requires careful handling due to its hazardous nature, indicated by the signal word "Danger." Molekula supplies L-(+)-Alaninol from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
