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 2,5-Dibromo-3-propylthiophene.
2,5-Dibromo-3-propylthiophene (CAS 1187577-36-1), molecular formula C7H8Br2S and molecular weight 284.01 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, bromine substitution, 2,5-Dibromo-3-propylthiophene is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 284.01 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.
As a certified reference material (CRM), 2,5-Dibromo-3-propylthiophene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
