Chemical Structure
Description
CATO supplies 2-Hydroxy-5-methylhexanoic acid (CAS 25915-36-0), a certified reference material (molecular formula C7H14O3, MW 146.18 g/mol) for analytical method development and quality control.
Structurally, 2-Hydroxy-5-methylhexanoic acid (C7H14O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 146.18 g/mol, it falls into the low-molecular-weight range.
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
