Description
CATO manufactures 2,5-dichloro-4-methylthiophene-3-carbaldehyde 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 2,5-dichloro-4-methylthiophene-3-carbaldehyde (CAS 210098-00-3), a certified reference material (molecular formula C6H8Cl2OS, MW 199.10 g/mol) for analytical method development and quality control.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, 2,5-dichloro-4-methylthiophene-3-carbaldehyde is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 199.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
