For procurement managers and R&D scientists in the chemical, pharmaceutical, and agrochemical industries, sourcing high-quality intermediates is a critical factor in project success. 1,4-Difluoro-2-methyl-5-nitrobenzene is one such chemical intermediate that demands careful consideration due to its complex structure and its vital role in advanced synthesis. This guide aims to equip B2B buyers with the knowledge needed to effectively source this compound, focusing on purity, specifications, and identifying reliable manufacturers.

The primary specification to scrutinize when purchasing 1,4-Difluoro-2-methyl-5-nitrobenzene is its purity. Typically, a purity level of ≥98% is required for most industrial and research applications. This ensures that the intermediate will perform reliably in downstream synthesis, minimizing the risk of side reactions and the generation of unwanted byproducts. Buyers should always request and review the Certificate of Analysis (CoA) from potential suppliers. This document provides detailed analytical data, often including results from Gas Chromatography (GC) or High-Performance Liquid Chromatography (HPLC), confirming the purity and identifying any trace impurities.

Beyond purity, understanding the physical characteristics is also important. 1,4-Difluoro-2-methyl-5-nitrobenzene is generally supplied as a colorless to light yellow powder. Its physical state and appearance can offer initial clues about its quality, though analytical data remains the definitive measure. Furthermore, information regarding its molecular formula (C7H5F2NO2) and molecular weight (173.12) should be readily available from the supplier and match expected values.

When looking to buy 1,4-Difluoro-2-methyl-5-nitrobenzene, especially in bulk quantities, identifying a reputable manufacturer is key. Several factors contribute to a supplier's reliability: a stable production capacity, consistent quality control, adherence to international standards, and transparent pricing. For businesses looking for cost-effective solutions without compromising on quality, exploring manufacturers in China can be a strategic move. Many Chinese chemical suppliers and manufacturers have advanced production capabilities and a strong export market presence.

Prospective buyers should engage with potential suppliers by requesting quotes that clearly outline pricing per kilogram or ton, lead times for delivery, and minimum order quantities (MOQ). Good suppliers will also provide comprehensive safety data sheets (SDS) and be responsive to technical inquiries. By focusing on these critical aspects – purity, detailed specifications, and the reputation of the manufacturer – B2B buyers can confidently source 1,4-Difluoro-2-methyl-5-nitrobenzene to meet their demanding synthesis requirements.
