(E)-4-(4-Chlorostyryl)thiophene-3-carbaldehyde CAS 1007388-21-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-4-(4-Chlorostyryl)thiophene-3-carbaldehyde.

(E)-4-(4-Chlorostyryl)thiophene-3-carbaldehyde (CAS 1007388-21-7), molecular formula C13H9ClOS and molecular weight 248.73 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, (E)-4-(4-Chlorostyryl)thiophene-3-carbaldehyde is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 248.73 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).

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.

CATO manufactures (E)-4-(4-Chlorostyryl)thiophene-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.
