MSMLS (Mass Spectrometry Metabolite Library of Standards) is a collection of high purity (>95%) small biochemical molecules that span a broad range of primary metabolism, supplied in an economical ready-to-use format. The library of standards are most commonly used to provide retention times and spectra for key metabolic compounds, help optimize mass spectrometry analytical protocols, and qualify and quantify mass spectrometry sensitivity and limit of detection.

 MSMLS Kit Contents:

Over 600 unique compounds arrayed in seven (7) 96-well plates

Plate Map

User Manual

MLSDiscovery software tool with user guide to support the extraction, manipulation, and storage of the data generated using LC-MS.

Features and Benefits

Broad Spectrum Key Primary Metabolite Compounds
Over 600 unique small molecule metabolites covering key metabolic pathways.


Compounds are pre-weighed and conveniently provided at 5 µg per well, enough for multiple injections. Discovery software is provided to help construct MS libraries, useful for metabolomic compound ID.

  • Arrayed in 96-well format
  • 7 polypropylene racks
  • Supplied as 5 µg dried weight
  • Alphanumeric assigned position 
  • Descriptors: Molecular formula, CAS, ChEBI, HMDB ID, METLIN ID, PubChem IDs
  • Suitable for manual and automated work flow

Preparation Instructions

Compounds can either be used as standards and injected individually or a strategy may be employed to pool compounds to allow multiple mixtures to be analyzed per injection.  For more information, please refer to the Product Sheet.


Recommended storage once solubilized at –20 °C, long-term at –80 °C; protected from moisture and light.  Avoid repeated freeze/thaw cycles.
