In the realm of fine chemicals and pharmaceutical intermediates, understanding the precise properties and purity of a compound is non-negotiable. Cellotetraose, identified by its CAS number 38819-01-1, is a critical oligosaccharide with significant applications, and its quality is directly tied to its performance. This article provides a detailed look at the essential properties and purity considerations for Cellotetraose, aimed at informing procurement specialists and R&D scientists.

The Chemistry of Cellotetraose (CAS 38819-01-1)
Cellotetraose is a linear tetrasaccharide composed of four β-(1→4)-linked D-glucose units. Its molecular formula is C24H42O21, and it has a molecular weight of approximately 666.58 g/mol. Typically appearing as a white to off-white powder, its solubility in water is a key attribute for many laboratory and industrial processes.

Purity Standards: What Buyers Must Know
The purity of Cellotetraose is a critical determinant of its efficacy in various applications. While some suppliers may offer material with purity levels of ≥85%, for demanding sectors like pharmaceuticals and advanced biochemical research, a purity of ≥95% or even ≥99% is often required. High-purity Cellotetraose ensures:

• Reproducible Results: In research settings, consistent purity minimizes variability in experiments.
• Formulation Stability: Pharmaceutical and cosmetic applications benefit from the predictability that high purity affords.
• Reduced Contamination: Minimizing impurities is vital for safety and regulatory compliance.

When sourcing Cellotetraose, always verify the Certificate of Analysis (CoA) provided by the manufacturer. A detailed CoA should specify the purity determination method (e.g., HPLC), alongside other critical parameters like melting point, optical rotation, and solubility. Reputable suppliers, such as those with ISO certifications, will readily provide this documentation.

Key Physical and Chemical Properties
Understanding the physical and chemical properties of Cellotetraose is essential for proper handling, storage, and application:

• Appearance: Typically a white to off-white powder.
• Melting Point: Around 251 °C (with decomposition), though variations may exist based on purity and specific crystal forms.
• Optical Activity: Possesses specific optical rotation, which is an important identifier.
• Solubility: Readily soluble in water, facilitating its use in aqueous solutions.
• Stability: Stable under recommended storage conditions, usually cool and dry environments.
