For professionals in the chemical and pharmaceutical industries, a deep understanding of product specifications is crucial for successful procurement and application. N-(4-Bromobutyl)phthalimide, with CAS number 5394-18-3, is a vital organic intermediate, and knowing its detailed specifications ensures its effective use in synthesis and research.

Product Name and CAS Number: The compound is consistently identified as N-(4-Bromobutyl)phthalimide, and its unique Chemical Abstracts Service (CAS) registry number is 5394-18-3. This unique identifier is essential for accurate sourcing and regulatory compliance.

Appearance: Typically, N-(4-Bromobutyl)phthalimide is supplied as a solid powder. The color can range from white to a light brown. This visual characteristic is an initial indicator of product quality, though it should always be verified with other analytical data.

Purity: Purity is a paramount specification for any chemical intermediate. N-(4-Bromobutyl)phthalimide is commonly available at a purity of 98% or higher, often confirmed through techniques such as Nuclear Magnetic Resonance (NMR) spectroscopy. High purity is critical to prevent side reactions and ensure the desired outcome in complex synthesis pathways, particularly in pharmaceutical applications.

Melting Point: The melting point is a key physical property used for identification and purity assessment. For N-(4-Bromobutyl)phthalimide, the reported melting point is generally in the range of 76-80°C. Minor deviations might occur depending on the specific batch and supplier, but a significant departure could indicate impurities or incorrect identification.

Solubility: Understanding the solubility of N-(4-Bromobutyl)phthalimide is important for experimental design. It is generally reported as soluble in common organic solvents like ethanol and somewhat soluble in chloroform, but insoluble in water. This profile influences solvent selection for reactions and purification steps.

Molecular Formula and Weight: The molecular formula is C12H12BrNO2, giving it a molecular weight of approximately 282.13 g/mol. These fundamental data points are vital for stoichiometric calculations in synthesis.

When you intend to buy N-(4-Bromobutyl)phthalimide, always request a detailed specification sheet from the manufacturer or supplier. This document should include the CAS number, appearance, assay (purity), melting point, and other relevant analytical data. For bulk purchases, ensure the supplier can provide consistent specifications across different batches. For R&D chemists and procurement managers, scrutinizing these specifications is a non-negotiable step in securing a reliable chemical intermediate.
