For chemical professionals, understanding the precise specifications of any compound is the first step towards successful application. 1,3-Diaminoguanidine Monohydrochloride (CAS 36062-19-8) is no exception. Its utility in pharmaceutical synthesis and energetic materials production hinges on its purity and adherence to specific physical and chemical properties. This article highlights the critical specifications to consider when looking to buy this vital intermediate.

Core Specifications for 1,3-Diaminoguanidine Monohydrochloride:

  • Appearance: Typically described as a White Crystalline Powder or white to off-white crystalline powder. This visual cue is an initial indicator of quality.
  • Purity: This is arguably the most critical specification. For most applications, particularly in pharmaceuticals, a purity of ≥98% is minimum, with ≥99.0% often being the preferred standard. Higher purity minimizes unwanted side reactions and ensures the efficacy of the final product.
  • CAS Number: 36062-19-8. This unique identifier is crucial for ensuring the correct compound is sourced.
  • Molecular Formula: CH8ClN5.
  • Molecular Weight: 125.56 g/mol.
  • Melting Point: Typically reported in the range of 180-182 °C (with decomposition), serving as another indicator of identity and purity.
  • Water Content: Often specified as being ≤0.2%, as excess moisture can affect stability and reactivity.

The Importance of Purity

In pharmaceutical manufacturing, impurities in intermediates can lead to the formation of undesired by-products in the final API, potentially affecting safety and efficacy. Similarly, in energetic materials, even trace impurities can alter performance characteristics or stability. Therefore, securing 1,3-Diaminoguanidine Monohydrochloride from a reliable manufacturer that guarantees high purity (like 99.0%) is paramount. Companies often rely on suppliers like NINGBO INNO PHARMCHEM CO.,LTD. to provide Certificates of Analysis (CoA) detailing these specifications.

When you decide to purchase this compound, always request detailed product specifications and inquire about the price for different purity grades if available. This due diligence ensures you obtain the right material for your critical applications.
