For professionals in the chemical synthesis domain, the quality and specifications of raw materials like 6-Bromohexanenitrile (CAS 6621-59-6) are non-negotiable. Ensuring the correct purity, appearance, and physical characteristics of this organic intermediate is vital for achieving reproducible results and optimizing reaction yields. This guide aims to clarify the key specifications that buyers should focus on when sourcing this important chemical, whether for pharmaceutical intermediates, agrochemical applications, or fine chemical manufacturing.

The most critical specification for 6-Bromohexanenitrile is undoubtedly its purity. Reputable manufacturers typically offer this compound with a minimum purity of 97%, as confirmed by analytical techniques like Gas Chromatography (GC). Higher purity grades may also be available for highly sensitive applications, but the 97%+ standard generally ensures reliable performance in most organic synthesis processes. Beyond purity percentage, the appearance is also a key indicator; 6-Bromohexanenitrile is characteristically described as a clear to slightly yellow liquid. Any significant deviation in color or the presence of visible impurities should prompt further investigation into the product's quality.

Other important physical and chemical properties that buyers should be aware of include its molecular formula (C6H10BrN) and molecular weight (176.05 g/mol). The boiling point, typically around 134°C at 13 mmHg, and refractive index (n20/D 1.477) provide further data points for material identification and quality verification. When you purchase 6-Bromohexanenitrile, always request a Certificate of Analysis (COA) that details these specifications for the specific lot you receive. This document is your assurance of quality and compliance.

For those looking to buy 6-Bromohexanenitrile, understanding these specifications helps in selecting the right product and a trustworthy manufacturer. A supplier that readily provides detailed COAs and can discuss the analytical methods used for quality control is a strong indicator of their commitment to product excellence. Furthermore, inquiring about storage conditions, typically recommended as sealed and at room temperature, ensures proper handling and longevity of the chemical.

In conclusion, a meticulous approach to understanding the purity and specifications of 6-Bromohexanenitrile is fundamental for successful chemical synthesis. By prioritizing high purity (97%+) and verifying key physical properties through COAs, buyers can confidently source this essential intermediate. Partnering with experienced manufacturers who can supply this critical component reliably will support your ongoing projects in the pharmaceutical, agrochemical, and broader fine chemical industries.
