Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Hydroxy-3-methylhexanoic acid.
3-Hydroxy-3-methylhexanoic acid (CAS 58888-76-9), molecular formula C7H14O3 and molecular weight 146.18 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 3-Hydroxy-3-methylhexanoic acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 146.18 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.
As a certified reference material (CRM), 3-Hydroxy-3-methylhexanoic 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.
