4-Chloro-2-{[(4-chlorophenyl)methyl]sulfanyl}-5,6,7,8-tetrahydroquinazoline CAS 338776-91-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Chloro-2-{[(4-chlorophenyl)methyl]sulfanyl}-5,6,7,8-tetrahydroquinazoline.

4-Chloro-2-{[(4-chlorophenyl)methyl]sulfanyl}-5,6,7,8-tetrahydroquinazoline (CAS 338776-91-3) is a high-purity analytical reference standard with the molecular formula C15H14Cl2N2S and a molecular weight of 325.26 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution, 4-Chloro-2-{[(4-chlorophenyl)methyl]sulfanyl}-5,6,7,8-tetrahydroquinazoline is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 325.26 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), 4-Chloro-2-{[(4-chlorophenyl)methyl]sulfanyl}-5,6,7,8-tetrahydroquinazoline 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.
