Understanding the precise chemical profile of a compound is fundamental for its effective use in research and industry. 5-(4-Chlorobutyl)-1-cyclohexyl-1H-tetrazole, identified by its CAS Number 73963-42-5, is a compound that holds significant importance as a pharmaceutical intermediate and impurity. This article aims to provide a clear overview of its essential chemical and physical characteristics, as documented by manufacturers and suppliers like NINGBO INNO PHARMCHEM CO., LTD.

The molecular formula for this compound is C11H19ClN4, with a calculated molecular weight of approximately 242.75 grams per mole. Visually, it is described as a white solid. This physical state is typical for many organic intermediates and is a key characteristic noted during quality assessment. The compound's structure consists of a cyclohexyl ring attached to a tetrazole ring, which in turn is linked via a nitrogen atom to a four-carbon chain terminating in a chlorine atom. This specific arrangement of atoms contributes to its reactivity and its role in complex organic syntheses.

Key physical properties such as melting point are crucial for handling and storage. Sources indicate a melting point in the range of 49-52°C or 53-55°C, depending on the specific purity and crystalline form. These values are important for determining appropriate storage conditions, typically in a dry environment, often refrigerated (2-8°C or -20°C) to maintain stability. The boiling point is significantly higher, with predicted values around 425.2°C at atmospheric pressure, though decomposition may occur at such elevated temperatures. Its solubility profile also provides valuable insights; it is generally soluble in common organic solvents like chloroform, dichloromethane, ethyl acetate, DMSO, and methanol.

The significance of 5-(4-Chlorobutyl)-1-cyclohexyl-1H-tetrazole is underscored by its application as an impurity in the synthesis of Cilostazol. Pharmaceutical companies rely on accurate data regarding such compounds to ensure the quality and safety of their final drug products. Suppliers like NINGBO INNO PHARMCHEM CO., LTD. play a vital role in providing this chemical intermediate with consistent purity, enabling accurate identification and quantification in quality control processes. When considering to buy such a compound, referring to its detailed chemical profile is the first step towards successful implementation in research or production.
