For industrial buyers and R&D professionals in the chemical and pharmaceutical sectors, the acquisition of raw materials like 2,3-Dimethylanisole (CAS 2944-49-2) requires meticulous attention to specifications. Ensuring that the chemical meets precise quality standards is fundamental to the success of synthesis, formulation, and product development. This guide outlines the key specifications that industrial buyers should scrutinize when sourcing 2,3-Dimethylanisole.

Understanding the Core Specifications

When evaluating a potential supplier for 2,3-Dimethylanisole, the following specifications are paramount:

• CAS Number: 2944-49-2. This unique identifier is crucial for ensuring you are referencing the correct chemical compound.
• Molecular Formula: C9H12O. This provides the basic elemental composition.
• Molecular Weight: Approximately 136.19 g/mol. This is important for stoichiometric calculations in synthesis.
• Purity: This is arguably the most critical specification. For industrial applications, a minimum purity of ≥97% is commonly required. For more sensitive applications, such as pharmaceutical intermediates, even higher purity levels might be specified. Purity is typically determined by Gas Chromatography (GC).
• Appearance: Typically described as a 'clear light yellow liquid'. Deviations from this could indicate contamination or degradation.
• Boiling Point (BP): Approximately 195°C. This physical property is a standard characteristic.
• Melting Point (MP): Around 29°C. While typically a liquid at room temperature, this is a useful reference point.
• Density: Approximately 0.984 g/mL at 25°C. This is important for handling, storage, and volumetric measurements.

Key Documents and Certifications for Industrial Buyers

Beyond the basic specifications, industrial buyers should always request and review supporting documentation:

• Certificate of Analysis (CoA): A CoA is essential. It details the actual test results for a specific batch, confirming that it meets the stated specifications for purity, appearance, and other key parameters. It should include lot number, test date, and assay results.
• Material Safety Data Sheet (MSDS) / Safety Data Sheet (SDS): This document provides critical information on the chemical's hazards, safe handling procedures, storage recommendations, and emergency measures. It is vital for workplace safety and regulatory compliance.
• Supplier Certifications: While not always mandatory for every intermediate, certifications like ISO 9001 demonstrate a manufacturer's commitment to quality management systems. For pharmaceutical applications, adherence to Good Manufacturing Practices (GMP) principles may be required, though intermediates often fall outside full GMP compliance unless specified.

The Role of Manufacturers and Suppliers

When you look to 'buy 2,3-Dimethylanisole' or seek a '2,3-Dimethylanisole manufacturer', understanding these specifications is your primary tool. Reputable suppliers and manufacturers, particularly established ones in China, will readily provide these details. They understand that their clients, whether they are product formulators or R&D scientists, rely on this precise information to ensure the integrity and success of their own processes.

Engaging with a supplier who can provide comprehensive data, including clear CoA for each batch and readily available SDS, fosters trust and minimizes risks. For procurement managers, verifying these specifications before placing an order for 2,3-Dimethylanisole ensures that the purchased material will perform as expected, safeguarding project timelines and product quality.
