CAS 497-09-6 — L-(-)-Glyceraldehyde

L-(-)-Glyceraldehyde is a naturally occurring triose sugar and key intermediate in carbohydrate metabolism, widely used in biochemical research, pharmaceutical synthesis, and chiral building blocks for asymmetric organic reactions. This optically active aldehyde serves as a precursor in the production of amino acids, nucleotides, and other biologically active compounds. L-(-)-Glyceraldehyde appears as a hygroscopic, colorless to pale yellow crystalline solid with a CAS number of 497-09-6, molecular formula C3H6O3, and a molecular weight of 90.0779 g/mol. It requires storage at +4°C and carries no signal word for hazard classification. Molekula supplies L-(-)-Glyceraldehyde from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
