CAS 609-06-3 — L-Xylose

L-Xylose is a naturally occurring pentose sugar found in plant materials like straw, corn cobs, and hardwoods, widely used in pharmaceuticals, food science (as a low-calorie sweetener or prebiotic), and biochemical research. It serves as a substrate for microbial fermentation, a diagnostic reagent, and a building block in synthetic chemistry. This white crystalline powder has a CAS number of 609-06-3, is non-hazardous (no signal word), and is soluble in water. It typically appears as a fine powder with a melting point of ~144°C and optical rotation of +19°C. Molekula supplies L-Xylose from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
