(S)-12-Hydroxyoctadecanoic acid CAS 18417-00-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-12-Hydroxyoctadecanoic acid.

(S)-12-Hydroxyoctadecanoic acid (CAS 18417-00-0), molecular formula C18H36O3 and molecular weight 300.48 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (S)-12-Hydroxyoctadecanoic acid (C18H36O3) 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 300.48 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), (S)-12-Hydroxyoctadecanoic 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.
