Understanding the precise chemical and physical characteristics of a compound is fundamental to its successful application in industry. 3-Aminophenol, known by its CAS number 591-27-5, is an organic compound whose specifications are critical for its widespread use as a chemical intermediate. Typically presenting as an off-white crystalline powder, its properties dictate its suitability for applications ranging from pharmaceutical synthesis to the creation of vibrant dyes.

The molecular formula for 3-Aminophenol is C6H7NO, with a molecular weight of approximately 109.13 g/mol. This structure, featuring both an amine (-NH2) and a hydroxyl (-OH) group attached to a benzene ring, is the source of its chemical reactivity and versatility. High purity levels are paramount, with industrial standards often requiring assay values of 99.5% or higher, typically verified by High-Performance Liquid Chromatography (HPLC). Low levels of impurities, such as water content (often specified to be ≤0.3%) and ash content (≤0.1%), are also crucial indicators of quality.

The physical properties of 3-Aminophenol are equally important. Its melting point generally falls within the range of 119-123°C, providing a stable solid form for handling and processing. While boiling point information is available (around 164°C at 11 mmHg), its primary utility often lies in its reactions as an intermediate rather than a volatile solvent. For manufacturers and suppliers like NINGBO INNO PHARMCHEM CO.,LTD., maintaining these precise specifications ensures that the 3-Aminophenol delivered consistently meets the stringent requirements of downstream processes, whether for complex pharmaceutical intermediate manufacturing or the demanding coloration standards in the dye industry.

Adherence to these specifications is not merely a matter of quality control; it directly impacts the efficiency and success of chemical syntheses. Ensuring minimal iron content and controlled heavy metal levels further solidifies its position as a reliable intermediate for sensitive applications. The consistent delivery of 3-Aminophenol that meets these detailed chemical profiles is what makes reputable manufacturers essential partners for industries globally.
