What Is Sucrose Standard Solution (10 mg/mL)?

Sucrose Standard Solution (10 mg/mL) is a certified reference solution containing sucrose—a non-reducing disaccharide composed of glucose and fructose—dissolved in purified water at a precisely verified concentration of 10 mg per milliliter. It is manufactured and quality-controlled to provide a traceable, reproducible benchmark for analytical measurements. Because sucrose is one of the most widely analyzed carbohydrates in biological, food science, and industrial research, a reliable standard solution is essential for generating accurate, comparable data across experiments and instruments.

Aladdin Scientific offers this standard under SKU P1507806A (currently archived). Researchers should contact Aladdin's technical support team or procurement to confirm current availability or identify an equivalent in-catalog replacement.

Key Applications in the Laboratory

Sucrose Standard Solution (10 mg/mL) supports a broad range of quantitative and qualitative laboratory techniques:

• HPLC Calibration: Used as an external or internal standard for high-performance liquid chromatography methods employing refractive index (RI) or evaporative light scattering detection (ELSD) to quantify sucrose in samples such as food matrices, plant extracts, and fermentation broths.
• Colorimetric Assay Validation: Serves as the calibration standard in classical carbohydrate assays including the phenol-sulfuric acid method and the anthrone method, enabling accurate construction of standard curves.
• Enzymatic Assay Controls: Provides a defined sucrose substrate concentration for invertase activity assays and other enzyme kinetics experiments.
• Method Development and Validation: Used during assay development to assess linearity, accuracy, and precision of new analytical methods requiring a carbohydrate reference.
• Quality Control: Incorporated into laboratory QC workflows to verify instrument performance and reagent integrity on each day of use.

Storage, Stability, and Handling

Proper storage and handling are critical to maintaining the accuracy and integrity of any standard solution. The following general guidelines apply to aqueous sucrose standard solutions; always defer to the specific conditions stated on the product Certificate of Analysis (CoA) or datasheet:

• Temperature: Store at 2–8 °C in a refrigerator. Do not freeze, as freeze-thaw cycles can alter the concentration through volume change or precipitation.
• Light Protection: Keep in the original amber or foil-wrapped container if supplied, or store in darkness to prevent potential photodegradation of the solution matrix.
• Container Integrity: Always reseal tightly after use to prevent evaporation, which would increase the effective concentration and introduce error into calibrations.
• Microbial Contamination: Sucrose solutions can support microbial growth over time. Inspect the solution for turbidity or color change before each use and discard if contamination is suspected.
• Expiry: Observe the expiry date printed on the label. Do not use beyond this date for quantitative analytical work.

Quality, Purity, and Regulatory Considerations

Standard solutions used for instrument calibration and method validation must meet defined purity and traceability requirements. While specific lot-level data for P1507806A should be obtained from the accompanying Certificate of Analysis, the following general quality considerations apply:

• Purity of Sucrose: High-quality sucrose standards are typically prepared from sucrose of ≥99% purity (often analytical or reagent grade) to minimize the contribution of impurities to measurement uncertainty.
• Concentration Accuracy: The stated concentration of 10 mg/mL should be verified gravimetrically or by a reference method during manufacture. Any uncertainty in the certified concentration should be stated on the CoA.
• Traceability: For regulated laboratory environments (e.g., GLP, GMP, ISO 17025-accredited labs), confirm whether this standard is traceable to a recognized national metrology institute (e.g., NIST, NMIJ).
• Solvent/Matrix: The standard is prepared in purified water; verify that no co-solvents, preservatives, or stabilizers are present that could interfere with your specific assay format.

Always request and review the CoA for each lot before use in critical analytical or QC workflows.
