For procurement specialists and R&D scientists in the chemical and pharmaceutical sectors, understanding the precise specifications of a raw material is critical for successful product development and manufacturing. 1-Methylcyclohexane-1,2-diol, bearing the CAS number 19534-08-8, is a compound that demands attention to detail regarding its characteristics. As a key pharmaceutical intermediate, its quality directly impacts the outcome of complex synthesis processes. This article outlines the essential specifications that buyers should look for when they intend to buy this compound.

Essential Chemical Identity and Properties

The fundamental identity of 1-methylcyclohexane-1,2-diol is established by its CAS number, 19534-08-8. Its molecular formula is C7H14O2, and its molecular weight is approximately 130.1849 g/mol. These are standard identifiers that should be readily available from any reputable manufacturer or supplier. Understanding these basic properties is the first step for any buyer.

Appearance and Purity: The Cornerstones of Quality

When sourcing 1-methylcyclohexane-1,2-diol, the physical appearance and purity are paramount. This compound is typically supplied as a white powder. The purity level is a critical parameter, with a standard expectation of 99%. This high purity is essential for its role as a pharmaceutical intermediate, where even minor impurities can affect downstream reactions or the final API's efficacy and safety. Buyers should always request a Certificate of Analysis (CoA) that confirms this 99% purity and details any specific impurity profiles.

Key Physical and Chemical Data

Further specifications that are vital for safe handling, storage, and application include:

  • Density: Reported at 1.095 g/cm³, this figure is useful for volume-to-mass calculations in formulation.
  • Flash Point: With a flash point of 104.5°C, it indicates the temperature at which the substance can vaporize to form an ignitable mixture in air, informing safety protocols.
  • Boiling Point: The boiling point is listed as 226.9°C at 760 mmHg, providing information for processes involving heating or distillation.

Sourcing Strategy and Supplier Reliability

When you need to buy 1-methylcyclohexane-1,2-diol, looking for a manufacturer or supplier that clearly presents these specifications is crucial. Reputable chemical suppliers, especially those in China specializing in pharmaceutical intermediates, will provide comprehensive technical data. Ensuring that the supplier can consistently deliver material meeting these precise specifications is key to a successful procurement process. Often, obtaining a sample for laboratory evaluation before placing a bulk order is a prudent step for critical applications.

In summary, a thorough understanding of the specifications for 1-methylcyclohexane-1,2-diol (CAS 19534-08-8)—particularly its appearance, 99% purity, molecular weight, and density—is non-negotiable for chemical buyers. Partnering with a trustworthy supplier that provides accurate and verifiable data ensures the quality and success of your chemical synthesis projects.
