In the chemical industry, the quality of raw materials directly dictates the success of manufacturing processes and the integrity of final products. For critical intermediates like 4-Amino-3-nitrophenol (CAS 610-81-1), robust quality assurance (QA) protocols are non-negotiable for any discerning buyer. Understanding these measures will help procurement managers and R&D scientists ensure they are sourcing consistently high-grade material.

Understanding the Quality Parameters of 4-Amino-3-nitrophenol

4-Amino-3-nitrophenol, a fine chemical essential for various synthetic applications, is typically specified by its CAS number 610-81-1. Key quality indicators include its physical appearance (often a deep violet crystalline powder), melting point range (typically 150-154°C), and, most importantly, its purity. Purity levels are commonly determined using techniques such as Gas Chromatography (GC) or High-Performance Liquid Chromatography (HPLC), with specifications often exceeding 98% for demanding applications.

The Role of Certificates of Analysis (CoA)

When you buy 4-Amino-3-nitrophenol, a Certificate of Analysis (CoA) is your primary document verifying its quality. A comprehensive CoA from a reputable manufacturer should detail:

  • Product identification (name, CAS number, molecular formula).
  • Physical appearance and characteristics.
  • Results from analytical testing (e.g., purity by GC/HPLC, moisture content, residual solvents).
  • Lot number for traceability.
  • Date of analysis and expiry/retest date.

As a chemical supplier, providing detailed and accurate CoAs is a fundamental aspect of our quality commitment. Buyers should always request and review the CoA before making a purchase.

Manufacturing Standards and Traceability

Reputable manufacturers of 4-Amino-3-nitrophenol adhere to strict manufacturing standards, often including ISO certifications. These standards ensure that production processes are controlled, documented, and consistently yield materials that meet predefined specifications. Traceability, from raw material sourcing through to the final product, is also a key component of QA, allowing for swift identification and resolution of any potential issues.

Why Source from Trusted Suppliers?

When you choose to buy 4-Amino-3-nitrophenol from a trusted supplier or direct manufacturer, you are investing in the reliability and efficiency of your own operations.
