NAD+

Description

NAD+ is the oxidized form of nicotinamide adenine dinucleotide, a naturally occurring pyridine nucleotide coenzyme composed of nicotinamide and adenine nucleotide units linked through phosphate groups. Research-grade NAD+ is utilized in controlled laboratory environments for analytical, biochemical, enzymatic, and molecular investigation. Its defined redox-active structure makes it suitable for studies involving coenzyme chemistry, enzyme interactions, and oxidation-reduction systems under controlled experimental conditions. The material is commonly supplied as a powder or lyophilized solid depending on the manufacturer and formulation.

Research Applications:

NAD+ may be utilized in controlled laboratory research settings for applications such as:

• Analytical characterization of nucleotide coenzyme identity and physicochemical properties
• Investigation of NAD+-dependent enzyme reactions in controlled biochemical assay systems
• Evaluation of oxidation-reduction behavior involving NAD+ and NADH under defined experimental conditions
• Examination of coenzyme stability, degradation, and molecular interactions in biochemical and cell-based research models

Storage and Handling:

• Store the material at -20°C or according to batch-specific supplier documentation.
• Protect from excessive moisture, heat, and prolonged light exposure.
• Handle prepared aqueous solutions according to validated stability data, as NAD+ stability can be influenced by temperature, pH, concentration, and buffer composition.
• Avoid unnecessary repeated freeze-thaw cycles and use appropriate laboratory handling procedures to minimize contamination and degradation.

Product Specifications:

• Purity: Refer to batch-specific HPLC, enzymatic, or other analytical results and Certificate of Analysis
• Appearance: Typically supplied as a white to off-white powder or lyophilized solid; verify against batch-specific documentation
• Solubility: Generally soluble in aqueous laboratory systems, with actual solubility dependent on concentration, pH, formulation, and solvent conditions

Compliance Notice:

NAD+ is FOR RESEARCH USE ONLY. It is not intended for human or veterinary use. This product is supplied exclusively for controlled laboratory, analytical, and in vitro research purposes and is not intended for diagnostic, therapeutic, or clinical applications. Misuse of this product is strictly prohibited and may violate applicable federal, state, or local laws. By purchasing this product, the buyer represents and warrants that it will be used solely for legitimate laboratory research purposes.

Technical Note: The molecular formula C₂₁H₂₇N₇O₁₄P₂ and molecular weight of approximately 663.43 g/mol correspond to the commonly referenced oxidized form of nicotinamide adenine dinucleotide (NAD+). Commercial materials may be supplied as different salts, hydrates, or formulation variants, which can affect reported molecular weight and analytical specifications. NAD+ should also be distinguished from NADH, its reduced form, which has different molecular properties. Final product-page specifications should therefore match the supplier documentation and the batch-specific Certificate of Analysis (COA).
