Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

1956-45-2 Ethanone, 1-(2-thienyl)-, oxime Ketone, methyl 2-thienyl, oxime 1-(2-Thienyl)ethanone oxime AI3-61792 EINECS 217-800-2 Methyl 2-thienyl ketone oxime NSC 16234 (CAS 1956-45-2), molecular formula C6H7NOS and molecular weight 141.19 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1956-45-2 Ethanone, 1-(2-thienyl)-, oxime Ketone, methyl 2-thienyl, oxime 1-(2-Thienyl)ethanone oxime AI3-61792 EINECS 217-800-2 Methyl 2-thienyl ketone oxime NSC 16234 (C6H7NOS) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 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 141.19 g/mol, it falls into the low-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.
