In the complex world of chemical synthesis, particularly within the pharmaceutical sector, the precise specifications of raw materials can dictate the success of a production run. Methyl 4-amino-2-methoxybenzoate, identified by its CAS number 27492-84-8, is a prime example of an intermediate where quality assurance is non-negotiable. For procurement managers and research scientists, understanding these specifications is key to making informed purchasing decisions.

The appearance of Methyl 4-amino-2-methoxybenzoate is typically described as a white to off-white crystalline powder. This physical characteristic is the first indicator of product quality and consistency. Beyond appearance, the assay is a critical metric, often required to be ≥99.0%. This high purity level ensures that the intermediate contributes effectively to the desired reaction pathway, minimizing side products and maximizing yield in downstream processes like Amisulpride synthesis.

Further essential specifications include the melting point, generally falling within the 155-160°C range, and a loss on drying limit of ≤0.5%. These parameters are indicative of the compound's stability and dryness, impacting its storage, handling, and reactivity. Equally important are the impurity controls, with limits typically set for single impurities (≤0.5%) and total impurities (≤1.0%). Adhering to these stringent impurity profiles is vital for pharmaceutical intermediates, as any contaminants could compromise the final drug product.

When you are looking to buy CAS 27492-84-8, working with a reputable manufacturer that provides comprehensive documentation, including detailed Certificates of Analysis, is highly recommended. These documents will confirm that the product meets all specified requirements, offering peace of mind to buyers. For companies seeking a reliable supplier, understanding these technical details ensures you acquire a material fit for purpose, contributing to the overall quality and safety of your manufactured products.
