Chemical Structure
Description
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.
(S)-2-(3,4,5-TRIMETHOXYPHENYL)BUTYRIC ACID (CAS 195202-08-5), molecular formula C13H18O5 and molecular weight 254.28 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, (S)-2-(3,4,5-TRIMETHOXYPHENYL)BUTYRIC ACID is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 254.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
