The occurrence of D-(+)-Trehalose Anhydrous is closely related to a carbohydrate-derived structure in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
D-(+)-Trehalose Anhydrous (CAS 99-20-7), molecular formula C12H22O11 and molecular weight 342.30 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carbohydrate-derived structure, D-(+)-Trehalose Anhydrous is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 342.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
