Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-Bromo-2-methylthiophene-3-carbaldehyde (CAS 1369356-10-4), molecular formula C6H5BrOS and molecular weight 205.07 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 5-Bromo-2-methylthiophene-3-carbaldehyde (C6H5BrOS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 205.07 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
