2-Hydroxy-3-methylpentanoic Acid (Mixture of Diastereomers) CAS 488-15-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Hydroxy-3-methylpentanoic Acid (Mixture of Diastereomers).

2-Hydroxy-3-methylpentanoic Acid (Mixture of Diastereomers) (CAS 488-15-3), molecular formula C6H12O3 and molecular weight 132.16 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-Hydroxy-3-methylpentanoic Acid (Mixture of Diastereomers) (C6H12O3) 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 132.16 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.
