In the sophisticated field of material science and chemical synthesis, the precise specifications of raw materials are not merely data points; they are critical determinants of product performance, process efficiency, and ultimate success. For R&D scientists and product formulators, understanding and critically evaluating these specifications is a core competency. This case study explores the importance of chemical specifications by focusing on D-Glucitol, 1,4:3,6-dianhydro-2,5-di-O-ethenyl (CAS 40268-97-1), an organic intermediate vital for advanced material applications.

D-Glucitol, 1,4:3,6-dianhydro-2,5-di-O-ethenyl is a colorless transparent liquid, with a defined molecular formula C10H14O4 and a molecular weight of 198.22 g/mol. These fundamental identifiers are the first layer of specification. They confirm the identity of the substance and provide basic physical and chemical context. However, for application-driven synthesis, deeper specifications are required.

When this intermediate is used in the production of polyurethane rigid foams, its contribution to key performance indicators becomes paramount. Manufacturers commonly report that its inclusion results in specific mechanical properties: high support strength, excellent compression resistance (typically 128-155 KPa), and a low density (26-34 kg/m³). These figures are derived from rigorous testing and form a crucial part of the material's application specification. An R&D scientist seeking to develop a lighter yet stronger insulating panel would specifically look for an intermediate that can reliably deliver these attributes.

For procurement and R&D teams, understanding the implications of variations in these specifications is vital. For instance, impurities in the D-Glucitol, 1,4:3,6-dianhydro-2,5-di-O-ethenyl can lead to unpredictable reaction kinetics, reduced foam strength, or compromised dimensional stability. This highlights the importance of sourcing from manufacturers with robust quality control systems, often evidenced by detailed Certificates of Analysis (COA) that specify purity levels, identify trace impurities, and confirm physical properties like density and boiling point (323.3±42.0°C at 760 mmHg).

The role of a reliable chemical supplier extends beyond simply delivering the product. A competent supplier will ensure that the CAS 40268-97-1 they provide meets the required application specifications consistently. They facilitate access to this vital intermediate, often sourced from dedicated manufacturers in China, making it available for purchase by research institutions and industrial formulators worldwide. Understanding the typical packaging (e.g., 25KG/Drum) and storage recommendations (clean, dry, cool place, away from sunlight and rain) also forms part of the complete product specification, ensuring its integrity from supplier to end-user.

In conclusion, for R&D scientists and product formulators, the detailed chemical and application specifications of organic intermediates like D-Glucitol, 1,4:3,6-dianhydro-2,5-di-O-ethenyl are indispensable tools. These specifications not only confirm material identity but critically guide synthesis and formulation to achieve desired end-product performance. Partnering with suppliers who prioritize transparency and quality in their specification data is fundamental for driving innovation in advanced materials.
