Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Aminothiophene-2-carbaldehyde.
3-Aminothiophene-2-carbaldehyde (CAS 56489-01-1) is a high-purity analytical reference standard with the molecular formula C5H5NOS and a molecular weight of 127.16 g/mol.
Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 3-Aminothiophene-2-carbaldehyde is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 127.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 3-Aminothiophene-2-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.
