Answer:500 mg of neat aspartame analytical standard.
Answer:CAS 22839-47-0; molecular weight 294.30 g/mol.
Answer:At 2–8 °C.
Supelco Aspartame Analytical Standard is a neat reference material for chromatographic measurement of the artificial sweetener aspartame. Aspartame is a methyl ester dipeptide with molecular formula C14H18N2O5, molecular weight 294.30 g/mol and CAS number 22839-47-0. The 500 mg analytical-standard pack is suitable for preparing calibration solutions and confirming retention characteristics in applicable HPLC and other validated chromatographic methods. Monitoring aspartame is relevant to food and beverage analysis as well as selected cosmetics and consumer-product formulations. Prepare standards gravimetrically with a compatible solvent, verify solubility and stability under the method conditions, and account for any dilution or sample-treatment steps during quantitative calculations. Use an appropriate chromatographic technique and an independent quality-control check to evaluate assay performance. Store the material at 2–8 °C as specified for this presentation. The product is an analytical standard and should not be confused with food-grade sweetener for consumption or with a ready-made solution containing an assigned concentration.
