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.
4-CHLORO-5-METHYLBENZENE-1,3-DIOL (CAS 3446-05-7), molecular formula C7H7ClO2 and molecular weight 158.58 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C7H7ClO2, 4-CHLORO-5-METHYLBENZENE-1,3-DIOL contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 158.58 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
