Product Profile
NAC Powder at a Glance
This N-Acetyl-L-Cysteine grade is identified by its AJI92 specification, fine-powder appearance and defined analytical controls.
Assay Basis
Understanding the NAC Assay Specification
The specification reports N-Acetyl-L-Cysteine content on both a dried basis and an as-is basis. These values describe the same material using different reporting bases.
Dried-Basis Assay
The dried-basis specification measures NAC content after accounting for moisture. The representative batch specification is 98.5%–101.0% on this basis.
As-Is Assay
The as-is specification reports NAC content in the material as tested, without converting the result to a dried basis. The listed specification is not less than 97%.

Formulation Fit
Working with NAC Powder in Formulations
Particle size and the characteristic odor of NAC can affect how the ingredient is evaluated in capsules, tablets, premixes and powder formulations.
Particle Size & Powder Handling
The specification includes 95% passing 80 mesh. For filling, compression or blending processes, evaluate the supplied powder against the handling requirements of your own equipment and formula.
Characteristic Odor
The specification records a characteristic odor. For flavored powders or other sensory-sensitive formulations, evaluate NAC with the complete ingredient system during product development.
Capsules, Tablets & Powder Blends
NAC powder can be evaluated for solid-dose and powder-based supplement formats where assay, particle size and finished-formula characteristics are part of the material selection.
