• N-Acetyl-D-Mannosamine


Description N-Acetyl-D-mannosamine, manufactured in bulk (GMP) at NZP, is a ubiquitous but rare monosaccharide involved in a range of metabolic processes. It is often used as a precursor in the chemical or enzymatic synthesis of the neuraminic acids found in glycolipids and glycoproteins.

In biological systems it is the precursor compound for the biosynthesis of the sialic acids especially N-acetylneuraminic acid (Neu5Ac, NANA). For this reason N-acetyl-D-mannosamine is of keen interest to scientists around the world. NZP's N-acetyl-D-mannosamine is top grade material suitable for all purposes, biological or synthetic.
CAS Number 676347-48-1


Molecular Weight 221.21 (Anhydrous)
Synonyms ManNAc; NAM; N-Acetylmannosamine monohydrate; DEX-M74
Use of Chemical N-Acetyl-D-mannosamine is becoming a favoured media component to enhance sialylation in CHO, BHK and HEK mammalian cell culture glycoprotein and mAb production

For application as a intermediate in chemical synthesis, please see N-acetyl-D-mannosamine (product code 75) which is better suited for these applications.

  • HILIC LC MS/MS methods for ManNAc and Neu5Ac in human plasma are described.
  • A fit-for-purpose approach was adopted during method validation and sample analysis.
  • A surrogate matrix, 5% BSA, was utilized for the preparation of calibration standards.
  • Extraction with a phospholipid removal plate eliminated matrix effect.
