For professionals in the chemical and pharmaceutical industries, a deep understanding of a compound's specifications is fundamental to successful procurement and application. 1-Naphthalenecarbohydrazide (CAS 43038-45-5) is no exception. As a key intermediate, its quality, purity, and physical properties directly impact the efficacy and outcome of synthesis processes. This article outlines the essential specifications of 1-Naphthalenecarbohydrazide and guides you on how to effectively source it from reliable manufacturers and suppliers.

Understanding the Key Specifications

When you intend to buy 1-Naphthalenecarbohydrazide, it's crucial to know what to look for. The most critical specification is typically its purity. Reputable suppliers will guarantee a minimum purity, often 95% or higher, as confirmed by analytical testing such as Gas Chromatography (GC) or High-Performance Liquid Chromatography (HPLC). For specialized applications, higher purity grades might be available. The compound's appearance is also important; 1-Naphthalenecarbohydrazide is generally described as a white to light yellow crystalline powder. This visual cue can sometimes indicate quality, although definitive purity testing is always recommended.

Other significant physical properties include its melting point, which for 1-Naphthalenecarbohydrazide is consistently reported in the range of 166-168°C. This consistent melting range is a strong indicator of product integrity. The molecular formula (C11H10N2O) and molecular weight (186.21 g/mol) are also standard identifiers that ensure you are procuring the correct chemical entity. Stability under normal storage conditions is another factor; it is typically stable under normal temperature and pressure, but proper storage in a tightly closed container in a cool, dry, well-ventilated area is advised.

Sourcing Strategies for Procurement Managers

Procurement managers seeking to buy 1-Naphthalenecarbohydrazide will find numerous options, especially from manufacturers in China. The key to successful sourcing lies in identifying dependable suppliers who can consistently deliver high-quality products. When evaluating potential suppliers, consider the following:

  • Quality Control: Does the manufacturer provide comprehensive Certificates of Analysis (CoA) with each batch?
  • Sample Availability: Can you obtain a free sample for testing before placing a large order?
  • Production Capacity: Does the supplier have the capacity to meet your volume requirements, whether for R&D or bulk manufacturing?
  • Technical Support: Does the supplier offer technical assistance regarding product use or specifications?
  • Pricing: Compare pricing across multiple suppliers, ensuring you are comparing equivalent quality and quantities. Direct manufacturer pricing is often the most competitive.

A proactive approach to supplier vetting, including checking for industry certifications and customer testimonials, will help ensure you are working with a trustworthy 1-Naphthalenecarbohydrazide manufacturer.

Understanding Packaging and Delivery Options

Availability also extends to packaging. Suppliers typically offer 1-Naphthalenecarbohydrazide in various quantities, from grams for laboratory use to kilograms or even tons for industrial production. Understanding these options allows you to choose the most cost-effective and convenient packaging for your needs. Reliable manufacturers also provide clear information on shipping times and methods, ensuring timely delivery to your facility, whether you are located domestically or internationally.

Conclusion

Mastering the specifications of 1-Naphthalenecarbohydrazide (CAS 43038-45-5) is critical for any buyer in the chemical and pharmaceutical sectors. By prioritizing purity, understanding physical properties, and strategically sourcing from reputable manufacturers and suppliers, you can secure this essential intermediate with confidence. Always remember to request samples and thorough documentation to ensure the quality and suitability for your intended applications.
