In the realm of forensic science, precision and reliability are non-negotiable. The detection of gunshot residue (GSR) is a critical aspect of crime scene investigation, and the Griess Test remains a cornerstone for identifying the presence of nitrates, often indicative of firearm discharge. Central to the effectiveness of the Griess Test is the reagent N-(1-Naphthyl)ethylenediamine Dihydrochloride (NED·2HCl). As a specialized chemical supplier, we understand the stringent requirements of forensic laboratories and provide this vital compound with guaranteed quality.

The mechanism involves the reaction of nitrite ions (from nitrates) with sulfanilamide in an acidic medium, followed by coupling with N-(1-Naphthyl)ethylenediamine Dihydrochloride to produce a distinctive pink azo dye. This colorimetric reaction allows forensic analysts to visually confirm the presence of nitrates. For laboratories needing to buy N-(1-Naphthyl)ethylenediamine Dihydrochloride, sourcing from a reputable manufacturer in China like ourselves ensures access to a product with a consistent assay of 98% minimum, a crucial factor for the test’s sensitivity and specificity.

The chemical, identified by CAS number 1465-25-4 and molecular formula C12H16Cl2N2, is typically supplied as a gray powder. Proper storage in dry, ventilated areas is recommended to maintain its integrity. Forensic professionals rely on the availability of this reagent for routine analysis and case investigations. We offer competitive N-(1-Naphthyl)ethylenediamine Dihydrochloride pricing, making it accessible for departments with varying budgets, while maintaining the high standards required for forensic applications.
