Lactose monohydrate reference standard EP is a high-purity analytical grade of lactose used for pharmaceutical testing, quality control, and calibration in laboratories to ensure compliance with European Pharmacopoeia (EP) standards. Lactose itself serves as a tablet and capsule excipient and diluent, a component of microbiological culture media, and a substrate for lactic acid fermentation in foods and silage. This reference material is essential for validating lactose-based formulations, assays, and dissolution tests in drug development. Catalogue reference Y0001750 features a CAS number of 64044-51-5, molecular formula C12H22O11·H2O, and a molecular weight of 360.32 g/mol. It requires ambient storage, carries no signal word for hazard classification, and is supplied with full documentation. Molekula supplies Lactose monohydrate reference standard EP from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
