Selecting the appropriate indicator is fundamental to achieving accurate and reproducible results in chemical analysis, particularly in acid-base titrations. Orange IV, identified by CAS 554-73-4, stands out as a preferred choice for many chemists due to its distinct properties and broad applicability. NINGBO INNO PHARMCHEM CO.,LTD. provides this crucial reagent to support the analytical community.

The primary advantage of Orange IV lies in its clear visual transition. As an acid-base indicator, it exhibits a sharp color change from red to yellow within a specific pH range (1.3-3.2). This range makes it exceptionally useful for titrations involving strong acids and weak bases, where the endpoint occurs within this pH window. The precise use of Orange IV as an acid base indicator ensures that analysts can confidently identify the equivalence point, leading to accurate concentration determinations.

Beyond its role in titrations, Orange IV is recognized as a versatile colorimetric analysis reagent. Its ability to signal changes in chemical environments extends its utility to applications such as sensors and indicators for product exceeding threshold temperature. This versatility means that a single, high-quality reagent can serve multiple analytical needs within a laboratory or industrial setting.

When considering the purchase of Orange IV, the reliability of the supplier is paramount. NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing CAS 554-73-4 that meets stringent quality standards. This ensures that the indicator will perform consistently, offering sharp color changes and predictable behavior, which are essential for maintaining the integrity of analytical data. The solubility of Orange IV in water and ethanol further adds to its ease of use.

For laboratories and industries that rely on accurate chemical analysis, choosing Orange IV is a strategic decision. It offers a combination of sensitivity, distinct visual cues, and broad applicability. NINGBO INNO PHARMCHEM CO.,LTD. is your trusted partner for sourcing high-quality Orange IV, ensuring your analytical processes are robust and reliable.
