Chemical Structure

L-(+)Sodium Glutamate CAS 142-47-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 169.11 g/mol gives L-(+)Sodium Glutamate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

L-(+)Sodium Glutamate (CAS 142-47-2), molecular formula C5H8NO4Na and molecular weight 169.11 g/mol, is a CATO reference standard with documented purity and traceability.

L-(+)Sodium Glutamate (C5H8NO4Na) contains a carbohydrate-derived structure, an amide group. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), L-(+)Sodium Glutamate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
