For procurement managers and R&D scientists in the chemical and pharmaceutical sectors, a thorough understanding of a compound's specifications is crucial before making a purchase. 2,3,4-Trimethoxybenzaldehyde (CAS 2103-57-3) is a prime example of a chemical intermediate where precise knowledge of its properties and purity directly influences its successful application.

Physically, 2,3,4-Trimethoxybenzaldehyde typically presents as a white to pale yellow crystalline powder. Its melting point, commonly cited in the range of 38-41°C, is a key indicator of its solid state at ambient temperatures. The molecular formula is C10H12O4, with a molecular weight of approximately 196.20 g/mol. These basic physical and chemical properties are standard for many organic intermediates. However, for pharmaceutical applications, the real differentiators lie in its purity and the absence of critical impurities.

The essential specification for 2,3,4-Trimethoxybenzaldehyde, particularly when used as a pharmaceutical intermediate, is its assay or purity. Reputable suppliers will guarantee a minimum assay of ≥99.0% as determined by Gas Chromatography (GC). This high level of purity is critical for ensuring that the compound will perform predictably in synthesis reactions, especially in the demanding environment of API production. Furthermore, specifications often include limits for single impurities (≤0.5%) and total impurities (≤0.5%), along with moisture content (≤0.5%). These stringent controls are what distinguish a pharmaceutical-grade intermediate from a general-purpose chemical.

When sourcing 2,3,4-Trimethoxybenzaldehyde, understanding these specifications helps in selecting the right 2,3,4-Trimethoxybenzaldehyde supplier. For instance, if you are involved in the synthesis of Trimetazidine, ensuring the intermediate meets pharmaceutical standards is non-negotiable. Procurement managers should always request Certificates of Analysis (CoA) that clearly state the assay, impurity profiles, and moisture content. Inquiring about the price of 2,3,4-Trimethoxybenzaldehyde should always be paired with a review of these quality parameters to ensure value.

The chemical's CAS number, 2103-57-3, serves as a universal identifier, crucial for accurate ordering and research. For businesses looking to buy 2,3,4-Trimethoxybenzaldehyde, especially in larger quantities, identifying a reliable 2,3,4-Trimethoxybenzaldehyde manufacturer based in China can offer significant advantages in terms of cost-effectiveness and supply chain efficiency. However, the emphasis must always remain on verified purity and adherence to international quality standards.

In conclusion, a detailed understanding of the physical and chemical properties, particularly the purity specifications, of 2,3,4-Trimethoxybenzaldehyde is fundamental for any B2B buyer. This knowledge empowers informed decision-making, ensuring that the procured material meets the rigorous demands of pharmaceutical synthesis and other advanced chemical applications.
