5-Methylresorcinol anhydrous, also called orcinol, is a crystalline organic compound primarily used as a chemical intermediate in dyes, pharmaceuticals, and analytical reagents. It serves as a precursor in the synthesis of resorcinol-based polymers and is employed in biochemical assays as the orcinol (Bial's) reagent, which detects pentoses and RNA and stains sugars and glycolipids on thin-layer chromatography plates. This anhydrous chemical has a CAS number of 504-15-4, with the molecular formula CH3C6H3-1,3-(OH)2 and a molecular weight of 124.14. It is stored at ambient conditions and carries a signal word of *Warning* for safety classification. Molekula supplies 5-Methylresorcinol anhydrous from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
