Introduction: The Importance of Struktur Phenolphthalein

Known for its diagnostic utility and critical function in analytical chemistry, the struktur phenolphthalein molecule stands as a key indicator in acid-base titrations and a building block across various industries. Its widespread adoption is attributable to its unique colorimetric transformation under different pH conditions, making it indispensable in laboratory and industrial contexts. As a triarylmethane dye, its in-depth research history and ongoing innovation continue to fuel advancements in the fields of chemical manufacturing, pharmaceuticals, and quality control.

This blog post explores the detailed characteristics, data-driven manufacturer comparisons, regulatory metrics like cas number phenolphthalein, and deep dives into technical advantages. Additionally, tailored formulations and real-world case applications are highlighted to showcase the modern relevance of phenolphthalein derivatives.

Chemical and Physical Properties Overview

Structurally, phenolphthalein features a triaryl methane base, which imparts both versatility and reactive potential. The molecular formula is C₂₀H₁₄O₄, and its molar mass is 318.33 g/mol. Renowned for its chromatic transition in response to pH—which ranges from colorless in acidic environments to a vivid pink between pH 8.2 and 10.0—this property makes it a prime candidate for titration endpoints. Its melting point, 258–263 °C, and limited water solubility further define its application context.

Safety, purity, and stability profile are rigorously monitored, especially for high-purity phenolphthalein intended for pharmaceutical or analytical use. Modern production techniques yield impurity levels below 0.05%, and batch-to-batch consistency is ensured through tightly regulated QA/QC processes.

Understanding CAS Numbers: cas number phenolphthalein, phenolphthalein cas no

The Chemical Abstracts Service (CAS) assigns unique identifiers to chemical substances. For phenolphthalein, the CAS number is 77-09-8, a crucial reference in research, procurement, and regulatory compliance globally. This number grants traceability across supply chains and ensures harmonization in safety standards, import/export documentation, and industry certifications.

Regulatory agencies across the EU, US, and Asia require the precise declaration of the phenolphthalein cas no on technical datasheets, Safety Data Sheets (SDS), and international shipping documents. This transparency streamlines cross-border trade and helps prevent mishandling or misidentification of hazardous substances, meeting REACH, TSCA, and other guidelines.

Comparative Analysis of Global Manufacturers

Numerous manufacturers worldwide produce phenolphthalein, offering differing product purities, packaging formats, and technical support services. A data-driven analysis reveals critical distinctions in quality assurance, lead times, and regional availability. Below is a comparative table detailing leading suppliers, average purity levels, annual output, and key certifications.

As the table demonstrates, top-tier manufacturers couple high purity with regulatory credentials and reliability. Selecting a supplier requires balancing desired grade, logistical capabilities, and compliance needs. Custom contracts and technical support may further differentiate supplier offerings.

Technological Strengths and Custom Formulation Options

Advances in synthesis and purification have repositioned phenolphthalein as a highly specialized product. Modern chromatographic and crystallization techniques support the production of analytical, pharmaceutical, and industrial grades tailored for niche applications. Research-backed process optimizations have reduced residual impurity levels, enhancing the consistency, efficacy, and environmental footprint of resulting compounds.

Manufacturers now offer custom formulation services, enabling modification of physical form (powder vs. granule), buffer compatibility, and moisture content. Value-added services may include bulk packaging, bespoke molecular modifications, and on-demand production for integration into diagnostic kits or advanced research protocols. Continuous investment in R&D allows top suppliers to offer solutions for emerging markets such as environmental monitoring sensors and bioanalytical test kits.

Practical Applications and Pivotal Case Studies
