Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Bromobenzo[b]naphtho[2,1-d]thiophene.
5-Bromobenzo[b]naphtho[2,1-d]thiophene (CAS 76113-28-5) is a high-purity analytical reference standard with the molecular formula C16H9BrS and a molecular weight of 313.21 g/mol.
Owing to sulfur-containing functionality, bromine substitution, a polycyclic aromatic system, 5-Bromobenzo[b]naphtho[2,1-d]thiophene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 313.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 5-Bromobenzo[b]naphtho[2,1-d]thiophene 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.
