Methanol USP CRS (United States Pharmacopeia Chemical Reference Substance) is a high-purity, analytical-grade alcohol used as a solvent, reagent, and calibration standard in pharmaceutical, chemical, and laboratory applications. More broadly, methanol is a key feedstock for producing formaldehyde, acetic acid and MTBE, and is also used as an antifreeze and as a fuel. It serves as a reference material for quality control, testing, and research where precise, documented purity is critical. This product has a CAS number of 67-56-1, with the molecular formula CH3OH and a molecular weight of 32.04. It is stored at ambient conditions and carries a Danger signal word per GHS classification. Molekula supplies Methanol USP CRS from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
