In the complex world of chemical procurement, a thorough understanding of a product's specifications is paramount. For professionals sourcing organic intermediates, 3-Isopropoxypropylamine (CAS 2906-12-9) is a compound of interest, primarily used in the dye industry and broader chemical synthesis. This article breaks down the key properties of 3-Isopropoxypropylamine, providing procurement managers and R&D scientists with the essential data needed to make informed purchasing decisions.

At its core, 3-Isopropoxypropylamine is an organic amine characterized by its molecular formula C6H15NO and a molecular weight of approximately 117.19 g/mol. Its appearance is consistently described as a clear, colorless to light yellow liquid, a critical visual indicator of its purity. From a handling and storage perspective, its flash point of 42 °C signifies that it is a flammable liquid, necessitating appropriate safety measures in its storage and use. The recommended storage temperature is in a flammables area, indicating the need for well-ventilated spaces away from ignition sources.

Key physical parameters that influence its application include its boiling point, which is reported as 78-79 °C at 85 mm Hg. This moderate boiling point makes it suitable for various reaction conditions where controlled evaporation or distillation might be necessary. Its density is approximately 0.845 g/mL at 25 °C, a standard measurement for liquid chemicals. Furthermore, its refractive index (n20/D) is approximately 1.4195, a property often used for quality verification. Importantly, 3-Isopropoxypropylamine is miscible with water, which can be advantageous in aqueous reaction systems or for certain purification processes.

Chemists and formulators often rely on acidity and basicity data. The predicted pKa of 3-Isopropoxypropylamine is around 9.82±0.10, indicating it is a moderately strong base due to the amine group. This basicity is fundamental to its reactivity in acid-base reactions and as a nucleophile.

For procurement professionals looking to buy 3-Isopropoxypropylamine from manufacturers and suppliers, understanding these specifications is crucial for ensuring product suitability and quality. For example, a supplier's claim of '99% purity' should be validated against its documented properties. When sourcing from China, suppliers like NINGBO INNO PHARMCHEM CO.,LTD. provide these detailed specifications, along with information on packaging (e.g., 25kg/drum) and typical delivery times (3-5 days). This data empowers buyers to compare offerings effectively and select the most appropriate partner for their chemical sourcing needs, ensuring the intermediate performs as expected in its intended applications, whether as a dye intermediate or in other organic synthesis pathways.
