Chemical Structure
Description
The occurrence of 2-hydroxy-2-methylpentanoic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-hydroxy-2-methylpentanoic acid (CAS 28892-68-4), molecular formula C6H12O3 and molecular weight 132.16 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 2-hydroxy-2-methylpentanoic acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 132.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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.
CATO manufactures 2-hydroxy-2-methylpentanoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
