For procurement specialists and research scientists in the chemical and pharmaceutical industries, understanding the precise specifications and quality control protocols for key raw materials is non-negotiable. This is particularly true when sourcing compounds like 2-(1H-imidazol-5-yl)acetic acid hydrochloride, identified by its CAS number 3251-69-2. Ensuring the quality of this imidazole derivative directly impacts the success of downstream synthesis, research outcomes, and ultimately, the development of new products.

Decoding the Specifications of CAS 3251-69-2

When you plan to buy 2-(1H-imidazol-5-yl)acetic acid hydrochloride, you will encounter a standard set of specifications that are crucial for assessing its suitability for your application. These typically include:

  • Chemical Name and Synonyms: 2-(1H-imidazol-5-yl)acetic acid hydrochloride, alongside synonyms like 4-imidazole acetic acid hydrochloride, helps confirm product identity.
  • CAS Number: 3251-69-2 is the unique identifier, essential for accurate sourcing and regulatory compliance.
  • Molecular Formula and Weight: C5H7ClN2O2 and 162.57 g/mol provide fundamental chemical information.
  • Purity: This is arguably the most critical specification. Reputable manufacturers typically offer this compound at a purity of 98% minimum. Higher purity grades may be available for more demanding applications, and it's important to discuss your specific needs when requesting a quote.
  • Appearance: The typical description is 'White to light yellow Crystalline Powder,' which offers a preliminary visual check. Deviations from this could indicate potential quality issues or degradation.
  • Melting Point: A melting point range, such as 218-222 °C, serves as an indicator of purity and structural integrity.
  • Solubility: Being 'Soluble in water' is an important characteristic for many chemical processes and formulations.

The Importance of Manufacturer Quality Control

Beyond the listed specifications, the quality control processes employed by the manufacturer are paramount. A reliable supplier will have robust systems in place to ensure batch-to-batch consistency and adherence to quality standards. This often includes:

  • Analytical Testing: Utilizing techniques such as High-Performance Liquid Chromatography (HPLC) for purity analysis, Nuclear Magnetic Resonance (NMR) for structural confirmation, and Mass Spectrometry (MS) for molecular weight verification.
  • Certificate of Analysis (COA): A COA should accompany each batch, detailing the specific test results for that lot against the stated specifications. This document is a critical part of the procurement process for any B2B buyer.
  • Traceability: Manufacturers with good quality systems ensure full traceability of raw materials and production processes.
  • Storage and Handling: Proper storage conditions, such as maintaining an inert atmosphere and room temperature, are crucial for preserving the compound's integrity until it reaches the customer.

When seeking to purchase 2-(1H-imidazol-5-yl)acetic acid hydrochloride, especially from manufacturers in China, it is advisable to inquire about their specific quality control procedures. A supplier who readily provides detailed COAs and can answer technical questions about their production process is typically a strong indicator of a commitment to quality. For those looking to buy in bulk, understanding these quality assurances ensures that your investment in this pharmaceutical intermediate or research chemical will yield reliable and reproducible results.
