Chemical Structure

α-Methylglyceric Acid CAS 21620-60-0 chemical structure

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

α-Methylglyceric Acid (CAS 21620-60-0), molecular formula C4H8O4 and molecular weight 120.10 g/mol, is a CATO reference standard with documented purity and traceability.

α-Methylglyceric Acid (C4H8O4) contains a carbohydrate-derived structure. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

As a certified reference material (CRM), α-Methylglyceric Acid 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.
