CAS 106-60-5 — 5-Aminolevulinic acid

5-Aminolevulinic acid (ALA) is a non-toxic, naturally occurring amino acid essential in the heme biosynthesis pathway, widely used in photodynamic therapy (PDT) for cancer treatment, dermatology (e.g., acne and psoriasis), and agricultural applications as a plant growth regulator. It appears as a white to off-white crystalline powder, soluble in water and slightly soluble in ethanol. The product has no signal word under CLP classification, indicating low hazard under normal use. Purity is typically ≥98% (HPLC), with minimal heavy metal impurities (<10 ppm). Molekula supplies 5-Aminolevulinic acid from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
