Description
CATO manufactures Methyl 3-[(E)-[(dimethylamino)methylidene]amino]-4-phenylthiophene-2-carboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies Methyl 3-[(E)-[(dimethylamino)methylidene]amino]-4-phenylthiophene-2-carboxylate (CAS 1785934-36-2), a certified reference material (molecular formula C15H16N2O2S, MW 288.36 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Methyl 3-[(E)-[(dimethylamino)methylidene]amino]-4-phenylthiophene-2-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 288.36 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.
