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 4-(1,3-Oxazol-5-yl)phenylisothiocyanate.
CATO supplies 4-(1,3-Oxazol-5-yl)phenylisothiocyanate (CAS 321309-41-5), a certified reference material (molecular formula C10H6N2OS, MW 202.23 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 4-(1,3-Oxazol-5-yl)phenylisothiocyanate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 202.23 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), 4-(1,3-Oxazol-5-yl)phenylisothiocyanate 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.
