D(+)-Trehalose dihydrate min. 98 %, Ph. Eur., 100 g

D(+)-Trehalose dihydrate is a pharmacopoeia-grade carbohydrate supplied at a minimum purity of 98 % according to Ph. Eur. requirements. The compound has the empirical formula C₁₂H₂₂O₁₁ · 2 H₂O, a molar mass of 378,24 g/mol, CAS number 6138-23-4 and EG number 202-739-6. It belongs to the class of disaccharide hydrates widely used in formulation, stabilisation and analytical work where a defined trehalose source is specified. This grade is suitable for laboratories working under pharmacopoeial quality systems and for carbohydrate applications that call for Ph. Eur. compliance. The material is packed as 100 g in plastic and is offered by manufacturer Carl ROTH for routine bench and process use. Typical contexts include buffer and excipient preparation, lyophilisation support studies and reference work with non-reducing sugars. Clear identity data (CAS, EG number and molar mass) support straightforward documentation in quality-controlled environments. Choose this 100 g pack when a compact, well-characterised quantity of D(+)-trehalose dihydrate is required for method development or small-scale production trials.
